Expert Testimony in Standard of Care Cases: Why a Genuine Disagreement Is the Defence

In a contested standard-of-care matter the Board’s case is an expert opinion and the defence is another one. Physicians assume the tribunal weighs them and prefers the better. It does not — or rather, preferring one marginally is not enough, because the Board must establish its case by clear and convincing proof to a reasonable certainty. Where two qualified clinicians in the field genuinely disagree, that standard is difficult to meet. The defence is the disagreement.

A Board accusation alleging substandard care rests on a clinical opinion. Someone — a contracted reviewer, then perhaps a retained expert — read the records and concluded that the care departed from the standard of practice.

The physician’s response is another clinical opinion. And the natural assumption is that the tribunal compares them and goes with the more persuasive.

That assumption is wrong in a way that matters enormously. Under Ettinger v. Board of Medical Quality Assurance (1982) 135 Cal.App.3d 853 (official source), the standard of proof to revoke or suspend a physician’s license is clear and convincing proof to a reasonable certainty, not a mere preponderance of the evidence. A tribunal that finds the Board’s expert slightly more persuasive has not found the allegation established.

So the defence in a genuinely contestable standard-of-care matter is not to win the battle of experts. It is to establish that qualified clinicians in the field reasonably differ — because a conclusion cannot be held to a reasonable certainty in the face of credible professional disagreement.

This article sets out what that means for choosing an expert, what to establish about the Board’s expert, where the opinion chain begins, and how the standard should be put to the tribunal.

What the standard does to a conflict of opinion

The interaction between the burden and expert evidence is the whole of this article, so it is worth stating carefully.

Ettinger (official source) holds that the proper standard of proof in an administrative hearing to revoke or suspend a doctor’s license is clear and convincing proof to a reasonable certainty. The trailing phrase is doing work: it is not enough that the tribunal thinks the Board is probably right.

Apply that to a standard-of-care allegation. The Board’s expert says the care departed from the standard. The physician’s expert, comparably qualified and practicing in the same subspecialty, says it did not — or says the chosen course was one of several accepted approaches.

Under a preponderance standard the tribunal resolves that by preferring one. Under clear and convincing proof to a reasonable certainty, the existence of the disagreement is itself an obstacle: a proposition disputed by a qualified practitioner in the field is difficult to hold to a reasonable certainty.

Three consequences follow, and they reshape how a defence should be built.

The objective is not to defeat the Board’s expert but to establish that the question is genuinely contested among competent clinicians. Those are different cases, and the second is usually easier and more honest.

Quality of match matters more than volume. One expert in the same subspecialty, practicing in a comparable setting, addressing the specific cases, does more than three general experts.

And the standard must be stated. As Silva v. Superior Court (1993) 14 Cal.App.4th 562 (law.justia.com) demonstrates in the interim context, tribunals apply preponderance unless the higher standard is raised — the point developed in clear and convincing evidence (Clear and Convincing Evidence: The Standard That Protects Physicians and the Places It Does Not Reach).

Where the Board’s opinion comes from

Before answering an expert opinion, establish which opinion you are answering — because there may be several, produced by different people at different stages.

As set out in medical consultants in Board investigations (Medical Consultants in Board Investigations: The Physicians Who Decide Whether You Are Investigated), Board material identifies three distinct physician roles in enforcement: reviewers performing the section 2220.08 (official source) pre-referral screening; medical consultants employed within the investigative unit; and contracted expert reviewers.

So a matter reaching a hearing may involve a screening opinion formed on a paper record before any investigation, internal clinical advice that shaped what the investigation sought, and a retained expert opinion prepared for the proceeding.

Four questions to put through discovery under Government Code section 11507.6 (official source).

Who formed each opinion, and in what specialty and subspecialty are they certified and practicing?

What material did each receive? A screening opinion formed without the physician’s explanation, or without literature the physician supplied, was formed on a narrower record than the hearing record.

Is the testifying expert the same person who screened? Where they are, the earlier opinion is examinable and may have been formed before the physician was ever heard. Where they are not, the Board retained someone new — which is informative.

And do the opinions agree with each other? Divergence between a screening rating and a retained opinion is material a physician would want.

The general point: the opinion chain is longer than the accusation reveals, and the earliest link was forged with the least information.

Choosing the physician’s expert

The single largest determinant of a contested standard-of-care defence is the expert, and the selection criteria are narrower than physicians expect.

Subspecialty match, not specialty match. Section 2220.08 (official source) sets the Board’s own benchmark: pertinent education, training, and expertise to evaluate the specific standard of care issues raised. A defence expert should meet that standard at least as well as the Board’s. An interventional question needs an interventionalist.

Setting match. A decision made in a community hospital without immediate subspecialty backup is assessed differently from the same decision in a tertiary centre. An expert who practises in a comparable setting can say so credibly; one who does not will be examined on it.

Current practice. An expert actively practicing can speak to what the standard is now and was then. Retirement is not disqualifying but it invites the question.

Willingness to state the narrow proposition. The most useful evidence is frequently not that the care was excellent but that the chosen course was one of several accepted approaches on which competent practitioners differ. An expert who will only say the care was correct is less useful than one who will say the question is genuinely contested — because the second speaks directly to whether the allegation can be held to a reasonable certainty under Ettinger (law.justia.com).

And absence of disqualifying connection. A partner, a co-author, or a colleague at the same institution can be discounted on independence, which wastes the investment.

What to resist: retaining a nationally prominent name whose practice does not match the setting, and retaining several experts on the theory that volume helps. Neither does.

How to frame the question you put to the expert

The instruction given to an expert determines the answer, and physicians and inexperienced counsel routinely ask the wrong question.

The question that produces a weak opinion: was the care appropriate? That invites a global endorsement, which reads as advocacy and is easy to undermine on any imperfection in the record.

The question that tracks the legal test has three parts.

What was the standard of practice for this presentation, in this setting, at the time of the care? Not now — then. Guidance changes, and an expert applying current guidance to an earlier decision is applying the wrong benchmark.

Was the course taken within the range of accepted practice? This is the operative question. The standard of practice is a range, not a point, and evidence that the decision sat inside the range defeats an allegation of departure without requiring a claim that it was optimal.

And can a conclusion that the care departed from the standard of practice be held to a reasonable certainty? That is the Ettinger (official source) formulation, and an expert who addresses it directly gives the tribunal the finding it needs to make. An expert asked only whether the standard was met has answered a different question.

Two further instructions worth giving. Address the specific cases and the specific record, rather than general practice — opinions that generalise are discounted. And identify what would have changed the assessment, because an expert who can say what facts would have made the care substandard is more credible than one who cannot.

The brief to the expert should also include everything obtained through discovery under section 11507.6 (official source). An expert working from the physician’s account rather than the Board’s material is preparing to be surprised.

Examining the Board’s expert

Cross-examination in these matters succeeds on a small number of lines, and they are documentary rather than rhetorical.

Qualification against the statutory benchmark. Section 2220.08 (official source) requires pertinent education, training, and expertise for the specific standard of care issues raised. Establish the expert’s subspecialty, current practice, and whether they perform the procedure or manage the presentation at issue. An expert one step removed from the specific question is answerable on it.

Material reviewed. Ask what they received and what they did not. Under section 11507.6 (leginfo.legislature.ca.gov) this is discoverable, and screening opinions in particular are formed on a limited record — sometimes without the physician’s explanation or any literature the physician supplied.

Whether the standard applied was contemporaneous. An expert applying current guidance to an earlier decision has applied the wrong benchmark, and the version in force at the time is a documentary fact.

Whether the standard is a range. Most useful of all: an expert who concedes that competent practitioners could reasonably have taken a different course has conceded the point that matters under Ettinger (official source). Many will concede it, because it is true and because refusing looks unreasonable.

And the engagement history, where relevant. As noted in medical consultants in Board investigations (Medical Consultants in Board Investigations: The Physicians Who Decide Whether You Are Investigated), the Board’s own material (official source) records that experts are rated for future use on feedback from the investigator, the medical consultant, and the attorney. How many matters an expert has handled for the Board is a fair question.

What to avoid: attacking competence or integrity. It rarely lands, and it makes the physician appear to be litigating the expert rather than the case.

When the Board has no expert

A category of allegation deserves separate treatment, because it changes the analysis entirely: matters where no expert opinion is needed.

Some charges are documentary. Failure to maintain adequate records, prescribing outside a permitted scope, failing to respond to a Board inquiry, or a conviction-based ground do not require an opinion about clinical judgment. The evidence is a document, and the Ettinger (official source) standard applied to a document is a much lower obstacle than the same standard applied to contested clinical opinion.

That distinction should be drawn early in any matter, allegation by allegation, because it determines where to spend.

Where an allegation is documentary, expert evidence is largely wasted. An expert cannot make a missing record present, and an opinion that the undocumented care was nonetheless appropriate confirms the documentation problem while adding an unverifiable account.

Where an allegation is evaluative, expert evidence is the case.

Most accusations mix the two, and the mix is the strategic picture. A physician facing one documentary charge and three evaluative ones has a very different position from one facing four documentary charges — and under section 2234 (leginfo.legislature.ca.gov) a single sustained allegation can support discipline.

The practical consequence for negotiation: where the documentary charge is unanswerable and the evaluative ones are genuinely contested, the realistic outcome is a resolution addressing the documentary matter. Recognising that early produces better terms than contesting everything and conceding late — the analysis in settlement and stipulation (Settlement and Stipulation: The Resolution That Ends the Case and Starts the Record).

The retrospective-reasoning problem

The most common flaw in an adverse expert opinion is not incompetence or bias. It is that the opinion was formed knowing the outcome.

An expert reviewing a complaint knows what happened next. They know the diagnosis that was eventually made, the deterioration that occurred, the finding on the scan that was ordered later. That knowledge is unavoidable and it distorts assessment of a decision made without it.

The legal question is whether the care met the standard of practice on what was known at the time. The psychological reality is that a bad outcome makes the earlier decision look worse than it was.

Four ways this shows up, each answerable.

The opinion recites the outcome before assessing the decision. Where the narrative structure runs "the patient was later found to have X, and the physician failed to order Y," the reasoning has begun from the endpoint.

The presenting features are described using later knowledge. Symptoms characterised as classic for a condition are frequently only classic once the condition is known.

The alternative course is treated as obviously indicated. If ordering the test were clearly indicated on the presentation, the question is why it is not routine practice on that presentation — and the answer is usually that it is not.

And base rates are absent. An opinion that a rare diagnosis should have been suspected on non-specific features rarely engages with how often those features present benignly.

The response is to make the temporal frame explicit and hold everyone to it. Ask the expert what was known at the time, what the differential was on those features, and what proportion of such presentations turn out to be the condition in question — then ask whether a departure can be held to a reasonable certainty under Ettinger (law.justia.com) on that basis.

What the tribunal is actually deciding

Expert evidence is presented to a specific decision-maker for a specific purpose, and understanding both improves how it is deployed.

The forum is an administrative law judge of the Medical Quality Hearing Panel, sitting within the Office of Administrative Hearings (official source) under Government Code section 11371 (official source). A lawyer, not a clinician.

That has three consequences for expert evidence.

Clarity beats sophistication. An opinion a non-clinician can follow — what the presentation was, what the options were, why this one was reasonable — is worth more than one that is technically impeccable and opaque. Experts accustomed to peer audiences frequently pitch too high.

The judge is assessing whether the Board has met its burden, not adjudicating a clinical dispute on the merits. An expert who says plainly that competent practitioners differ has given the judge a route to the finding that the standard was not met. An expert who insists the Board’s expert is simply wrong invites the judge to choose, which is the weaker position for the physician.

And the judge writes a proposed decision containing findings, which the Board then acts on under section 11517 (leginfo.legislature.ca.gov). So the expert evidence has to be usable in a written finding — which favours propositions that can be stated crisply over accumulations of nuance.

The practical instruction: prepare the expert for the audience. A pre-hearing conference in which the expert is asked to explain the case to someone without clinical training is time better spent than further refinement of the report — and it surfaces where the opinion depends on assumed knowledge the judge will not have.

Cost, and the cheaper version

Expert evidence is the largest expense in a contested standard-of-care matter, and a physician who cannot fund it fully still has options worth knowing.

The full version: a retained subspecialty expert who reviews the complete record and the Board’s disclosed material, produces a written opinion, and testifies at hearing. That is the strongest position and it is expensive.

The cheaper interventions, in ascending order of cost.

Contemporaneous literature. Guidelines and society statements in force at the time cost nothing but time to assemble, and they establish the range of accepted practice documentarily. As set out in medical consultants in Board investigations (Medical Consultants in Board Investigations: The Physicians Who Decide Whether You Are Investigated), section 2220.08 (leginfo.legislature.ca.gov) expressly contemplates physician-supplied literature at the screening stage — the cheapest and earliest point of all.

A short screening-stage opinion. A subspecialty colleague’s written view, obtained early, is a fraction of the cost of hearing testimony and lands where most matters are disposed of.

An opinion for negotiation rather than hearing. A credible expert view that the question is genuinely contested changes what the Attorney General (oag.ca.gov) can expect to prove under Ettinger (law.justia.com), and therefore changes the terms available — without anyone testifying.

And cross-examination alone. Where funds do not extend to a defence expert, the concession that competent practitioners could reasonably differ can sometimes be obtained from the Board’s own expert, who has professional reasons not to deny it.

The honest limitation: none of these fully substitutes for a matched expert at hearing, and a physician facing a serious evaluative allegation without one is disadvantaged. But the sequence above puts the cheapest and earliest interventions first, which is where they do most good.

What an expert cannot do

A caution, because physicians retain experts expecting them to solve problems that are not evidentiary.

An expert cannot supply a missing record. Where documentation is absent, an opinion that the undocumented care was appropriate rests on the physician’s account of what was done — which is unverifiable and, in a matter that also charges inadequate documentation, confirms the second allegation while addressing the first weakly.

An expert cannot resolve an admission. Where a physician has said in a written response or an interview that a step should have been taken and was not, an expert opinion that it need not have been contradicts the physician’s own statement. That is the mechanism by which the written response (The Physician’s Written Response: The Document That Decides Cases Before Anyone Calls It a Case) constrains everything downstream.

An expert cannot answer a documentary charge, as set out above.

An expert cannot make an outcome-driven case go away by asserting the outcome was unavoidable. The question is whether the decision was reasonable, not whether the harm was preventable, and conflating them concedes the frame.

And an expert cannot address penalty. Where an allegation is established, the sanction analysis under section 2227 (official source) is a separate exercise in which clinical opinion has limited purchase and remediation evidence has more.

The implication is that expert evidence should be deployed where it is decisive — on genuinely contested evaluative allegations — and not spread across a case as general support. A physician spending on an expert to address a documentation charge has bought the wrong thing, and the money would have done more work as a subspecialty opinion on the one allegation that turns on judgment.

The interim suspension exception

Everything above assumes a hearing on the merits. Expert evidence operates differently, and faster, where an interim order is sought.

Under Government Code section 11529 (leginfo.legislature.ca.gov) the Board may petition for an interim order suspending or restricting a license, and the showing is made on affidavits. Silva v. Superior Court (1993) 14 Cal.App.4th 562 (law.justia.com) holds that the applicable standard is clear and convincing evidence to a reasonable certainty — the same standard as at a merits hearing.

That combination is unusual and it favours the physician more than physicians realise. The Board must satisfy a demanding standard, on paper, at speed, on a prospective question about danger to the public.

Three consequences for expert evidence.

A responsive declaration matters disproportionately. On a paper record a subspecialty declaration is the evidence, and there is no opportunity to cure its absence later in the proceeding.

Speed is the constraint. A declaration obtained in days is worth more than a comprehensive report obtained in weeks, because the hearing will not wait.

And the target is the prospective element. The petition must show that continued practice will endanger the public health, safety, or welfare. An expert who addresses whether the specific risk is bounded, addressed, or manageable by conditions is answering the element most susceptible to defeat — as set out in interim suspension and emergency action (Interim Suspension and Emergency Action: Stopped From Practising Before Anything Is Decided).

The practical instruction: where an interim petition is a realistic prospect, identify the potential expert before it is filed. A physician served with a petition who then begins looking for a subspecialty colleague willing to declare within days is starting too late.

Where the opinion chain begins

A closing observation that reframes the whole subject, because it moves the decisive moment much earlier than a hearing.

The first clinical opinion in a quality-of-care matter is formed at screening, under section 2220.08 (official source), before any investigation. The statute requires that reviewer to consider the physician’s explanation and any expert testimony or literature the physician provides.

So the first opportunity to put expert evidence in front of a decision-maker is not at a hearing. It is in the ten working days after the Board requests information — at the point where most complaints are disposed of, before an accusation exists, before the Attorney General (oag.ca.gov) is involved, and before any expert has been retained against the physician.

That is the cheapest and highest-leverage moment in the entire process, and it is almost universally missed. Physicians send a narrative explanation and no literature; nobody sends a colleague’s opinion.

The economics are stark. A short subspecialty opinion at screening costs a fraction of hearing testimony and operates where the file is most likely to close. The same opinion obtained after an accusation is prosecuted has to overcome a retained Board expert, months of investigative material, and whatever the physician said in the interim.

The implication is the one this series keeps arriving at. The decisive interventions are early, they feel disproportionate at the time, and the causation runs opposite to the urgency. A physician who understands the Ettinger (law.justia.com) standard and acts on it at screening rather than at hearing is using it where it does most work — and the mechanics of that stage are set out in medical consultants in Board investigations (Medical Consultants in Board Investigations: The Physicians Who Decide Whether You Are Investigated).

Serving as an expert for a colleague

Physicians are asked to do this, and the asking usually comes from a colleague in difficulty who does not know what they are asking for.

What the role requires. A written opinion addressing the specific record, the standard of practice in force at the time, and whether the course taken sat within the range of accepted practice — and, if the matter proceeds, testimony before an administrative law judge at the Office of Administrative Hearings (dgs.ca.gov), including cross-examination by the Attorney General (oag.ca.gov).

Four things to establish before agreeing.

Whether your expertise is genuinely pertinent to the specific issues. Section 2220.08 (official source) sets that standard for the Board’s reviewers and it is the right standard for a defence expert too. Declining a matter adjacent to your subspecialty protects the physician more than accepting it.

Whether you can review the complete record, including the Board’s disclosed material obtained under section 11507.6 (official source). An opinion formed on a partial record will be examined on what was missing.

Whether you can state the narrow proposition honestly. The useful evidence is that competent practitioners could reasonably have taken this course. If you cannot say that, say so early — an expert who withdraws at the report stage costs the physician money; one who concedes the point under cross-examination costs them the case.

And whether any connection compromises independence. Same institution, same group, co-authorship, or a close personal relationship will be raised.

One further caution. Your own opinion becomes part of a permanent record, and testifying as an expert is professional work like any other. Declining a matter you cannot support is not disloyalty — it is the only useful answer.

What good looks like in the finding

A closing test, because expert evidence succeeds or fails in the words of a written decision.

The administrative law judge produces a proposed decision, which the Board (official source) then acts on under section 11517 (official source). That document contains findings, and the question worth asking of any expert case is what finding it enables.

The finding a physician wants reads roughly: the evidence established a range of accepted approaches to this presentation, and the respondent’s course fell within it; accordingly the Board has not established a departure from the standard of practice by clear and convincing proof to a reasonable certainty.

Notice what that finding requires. Evidence that a range existed. Evidence locating the physician’s conduct inside it. And the Ettinger (official source) standard stated so the judge can apply it.

Notice also what it does not require: a finding that the care was optimal, that the Board’s expert was wrong, or that the outcome was unavoidable. Physicians push for all three and none of them is necessary.

So the discipline in preparing expert evidence is to work backwards from that sentence. Every element of the opinion should contribute to a finding a judge could write in those terms, and material that does not — general endorsement, criticism of the Board, argument about the complainant — should come out.

And where an allegation cannot support that finding because the evidence genuinely establishes a departure, the honest conclusion is that expert evidence is not the answer to that allegation, and the matter belongs in the analysis in settlement and stipulation (Settlement and Stipulation: The Resolution That Ends the Case and Starts the Record) under section 2227 (official source) instead.

Multiple patients, and the pattern allegation

Accusations frequently charge several patients together, and the aggregation changes what expert evidence has to do.

A single-patient allegation asks whether one decision sat within the range of accepted practice. A multi-patient allegation asks the same question of each — and adds an implicit further claim that the instances form a pattern.

That implicit claim is where physicians lose ground without noticing.

Address each case separately, on its own record. An expert opinion that treats the cases as a group invites the tribunal to do the same, and a group is easier to characterise as a pattern than four individually defensible decisions are.

Establish the differences between them. Where the presentations, settings, and available options differed, the cases are not instances of one practice. Where they genuinely are similar, the pattern claim is stronger and should be recognised as such.

Check the selection. Where the Board reviewed a large volume of a physician’s records and charged four, the ratio matters. An expert who can put the charged cases in the denominator — four instances out of several hundred comparable encounters — has supplied context the accusation omits, and it bears directly on whether a pattern can be held to a reasonable certainty under Ettinger (law.justia.com).

And remember the screening asymmetry. As set out in medical consultants in Board investigations (Medical Consultants in Board Investigations: The Physicians Who Decide Whether You Are Investigated), section 2220.08 (leginfo.legislature.ca.gov) screening does not apply to new complaints about a physician already under investigation — so later cases added to an open matter never received independent expert pre-review at all. Whether each charged case was screened is a discoverable fact under section 11507.6 (leginfo.legislature.ca.gov) and worth establishing.

A worked example

The argument is easier to see applied. Take a common fact pattern: a patient presented with abdominal pain, was managed conservatively, and was diagnosed some weeks later with a condition that earlier imaging would have detected.

The weak defence: our expert says the care was appropriate and the outcome was unavoidable. That invites the tribunal to weigh two opinions and decide which it prefers, and the second limb concedes the frame by arguing about outcome rather than decision.

The strong defence has four components, each answering the legal test rather than the complaint.

The presenting features, established from the record. What was documented on the day — the character of the pain, the examination findings, the absence of red-flag features. This is documentary, not opinion.

The range of accepted practice on those features at that time. Contemporaneous guidance establishing that conservative management with review is an accepted approach to that presentation. Also largely documentary.

The expert proposition, stated narrowly: on the features documented, conservative management with a defined review interval was within the range of accepted practice, and competent practitioners in the specialty would reasonably have taken that course.

And the base rate, where available: how often that presentation reflects the eventual diagnosis. An expert who can say that the great majority of such presentations are benign has shown why imaging is not the routine answer.

That structure supports the finding a judge can write — a range existed and the conduct fell inside it, so a departure is not established to a reasonable certainty under Ettinger (law.justia.com).

What it deliberately omits: any claim that the outcome was unavoidable, any criticism of the Board’s expert, and any assertion about the physician’s general record.

Timing the expert engagement

When an expert is retained affects what the opinion can do, and the useful order runs opposite to how most matters proceed.

At screening, under section 2220.08 (official source), an opinion is cheap and lands where most complaints close. Ten working days is the constraint.

Before an investigative interview, an opinion tells the physician which of their decisions are defensible and which are not — which is precisely what they need to know before answering questions. Physicians almost never do this, and it is the second-best moment.

After discovery under section 11507.6 (official source), an opinion can respond to the Board’s actual evidence rather than to the accusation. This is the point at which a full report should be commissioned, because earlier reports may need rewriting once the Board’s material is known.

Before settlement discussions, an opinion sets the negotiating position. A credible view that the central allegation cannot be established to a reasonable certainty under Ettinger (official source) changes what the Attorney General (official source) can expect, and therefore the terms.

And at hearing, the opinion is tested.

The common error is to retain at the fourth or fifth point and skip the first three. That produces a good report addressing a case whose shape was already set by an unadvised interview and an unsupported written response.

The cheaper sequence — short opinion at screening, short opinion before interview, full report after discovery — costs more in total than a single late report but reaches the moments where an opinion changes the outcome rather than merely documenting a position.

What to do with a favourable opinion

A closing practical point, because obtaining a good opinion is not the same as using it.

Do not simply file it. An opinion sitting in counsel’s file does nothing. Where it is favourable and the matter is pre-accusation, the question is whether to put it in front of the decision-maker — and at screening stage section 2220.08 (leginfo.legislature.ca.gov) expressly contemplates that physician-supplied expert testimony forms part of what the reviewer considers.

Decide deliberately whether to disclose early. Disclosing a strong opinion before an accusation may prevent one. It also tells the Board what it must answer, which allows it to retain a better expert. That is a genuine strategic judgment and it should be made explicitly rather than by default.

Where disclosure is right, disclose the whole opinion. A summary invites the inference that the full document is less favourable.

Use it in negotiation on the specific allegations it addresses. An opinion that defeats two of four charges supports a resolution confined to the other two — which is a better outcome than either contesting everything or conceding all four, and it is the analysis in settlement and stipulation (Settlement and Stipulation: The Resolution That Ends the Case and Starts the Record).

And ensure it is written to survive the sanction stage. Where an allegation is established despite the opinion, the analysis moves to penalty under section 2227 (leginfo.legislature.ca.gov), and an expert who has addressed the reasonableness of the decision has supplied mitigation material even where they did not defeat the charge — which the Board (mbc.ca.gov) considers in fixing terms.

Where this leaves a physician without funds

A closing acknowledgment, because most of this article assumes resources many physicians do not have.

The protection Ettinger (law.justia.com) provides operates at a hearing, and reaching a hearing with matched expert evidence is expensive. A physician who cannot fund that is not able to use the standard as fully as one who can — which is the distributional problem named in clear and convincing evidence (Clear and Convincing Evidence: The Standard That Protects Physicians and the Places It Does Not Reach) and it is real.

What remains available, in order of cost.

Contemporaneous literature costs time only, and it establishes the range of accepted practice documentarily rather than through opinion. Under section 2220.08 (official source) it can be supplied at screening, before any of the expensive machinery starts.

A colleague’s short written view, obtained informally, is a fraction of a retained opinion and may be enough to establish that the question is contested.

The concession from the Board’s own expert on cross-examination — that competent practitioners could reasonably differ — costs nothing beyond counsel’s time and is frequently obtainable, because refusing it looks unreasonable.

And the physician’s own testimony, properly prepared, addressing what was known at the time rather than defending the outcome.

None of that equals a matched subspecialty expert at hearing. But a physician who assembles literature, obtains one short opinion, and prepares carefully has a materially better position than one who spends nothing — and the sequencing matters more than the total, because material supplied at screening operates where most matters are decided rather than where the Attorney General (oag.ca.gov) has already committed to prosecuting.

Building the expert case

State the Ettinger standard — clear and convincing proof to a reasonable certainty — explicitly on the record.

Sort allegations into documentary and evaluative; expert evidence only does work on the second kind.

Retain an expert matched on subspecialty and practice setting, not on prominence.

Ask the expert whether the course taken was within the range of accepted practice — not whether the care was appropriate.

Have the expert address the contemporaneous standard, not current guidance.

Ask the expert directly whether a departure can be held to a reasonable certainty.

Brief the expert on everything obtained through discovery, not just the physician’s account.

On cross-examination, seek the concession that competent practitioners could reasonably differ.

Establish what material the Board’s expert received, and whether the screening reviewer and testifying expert are the same person.

Where funds are limited: contemporaneous literature first, then a short screening-stage opinion, then an opinion for negotiation.

Establish the disagreement, not the answer

Physicians instinctively want their expert to say the care was correct. That is a stronger claim than the defence requires and a weaker position than the one available.

The Board must establish a departure from the standard of practice by clear and convincing proof to a reasonable certainty. A tribunal cannot hold that to a reasonable certainty if a qualified practitioner in the same subspecialty says the course taken was within the range of accepted practice.

So the proposition to establish is that the question is genuinely contested among competent clinicians — which is usually true, easier to prove, harder to attack, and directly responsive to the legal test. An expert who insists the care was optimal invites the tribunal to choose between experts. An expert who says reasonable practitioners differ removes the tribunal’s ability to reach the required degree of certainty at all.

General educational information—not legal or medical advice

This article describes California administrative practice and case authority for physicians and health lawyers. It is not legal advice and creates no professional relationship. The value of expert evidence in a particular matter is fact-specific, procedures and Board practice change, and nothing here substitutes for counsel experienced in California licensing defence working with an appropriately qualified expert.

Questions worth asking

Which allegations are evaluative and which are documentary?

Is our expert matched on subspecialty and on practice setting?

Has our expert addressed the standard in force at the time, or current guidance?

Will our expert state that the course taken was within the range of accepted practice?

Who formed the Board’s opinion, on what material, and is that person testifying?

Did the screening reviewer have the pertinent expertise for the specific issues raised?

Has the Ettinger standard been stated on the record, and by whom?

Takeaway

In a contested standard-of-care matter the defence is not a better expert but a genuine disagreement. Because Ettinger requires clear and convincing proof to a reasonable certainty, an allegation disputed by a qualified practitioner in the same subspecialty is difficult to establish — so the proposition to prove is that the course taken sat within the range of accepted practice, not that it was optimal. Expert evidence does no work on documentary charges, cannot repair a missing record or an admission, and is cheapest and most effective at the section 2220.08 screening stage, where almost nobody uses it.
