What was disputed, and how it came out

Each issue the panel decided, with the reasoning it gave. An outcome is what this panel did on this record — not a rule, and not a prediction.

The defendant failed to meet its burden of proof for apportionment because Dr. Mandell's opinions lacked the required how and why explanations, making them conclusory and not substantial evidence. Therefore, the applicant is entitled to an un-apportioned award of 54%.

From the decision · page 9AME Dr. Mandell discusses apportionment in his 3/3/21 Deposition, Joint Exhibit SS, EAMS Doc ID # 58328787. Dr. Mandell also discusses apportionment in his report dated 3/16/24, Joint Exhibit FF EAMS Doc ID # 58328791. This Court reviewed all of AME Dr. Mandell's remaining reports in this case: joint exhibits GG, HH, II, J, KK, LL, and MM. None of these reports provide any reasoning to support AME Dr. Mandell's non-industrial apportionment opinion. There is no how and why explanation. Defendant failed to meet its burden of proof for this affirmative defense. Therefore, Applicant is entitled to an un-apportioned award of 54%.

The facts that decided it

What the panel treated as outcome-determinative, and which side it favoured.

Dr. Mandell's MMI opinions were inconsistent, ambiguous, and speculative, including use of the word 'probably'.

Favours Applicant prevailed

This undermined the credibility of Dr. Mandell's opinion and led to rejection in favor of Dr. Fletcher's unequivocal opinion.

From the decision · page 6Furthermore, the inconsistent, ambiguous and speculative characteristics of Dr. Mandell's MMI opinions are summarized in the following questions and answers during the 4/16/25 deposition. Page 15; 21 to page 16; 14: Q. Okay. The problem we're having is you previously testified that it would be reasonable to assign the P & S date to when she went back to work after this procedure just as you did in the 2023 report but now we're back to the one-year status. So I'm a little confused as to what we're going off of to make that decision and is it within a reasonable medical probability? A. Well, I was being abundantly cautious when I said that she was permanent and stationary when she returned to work because obviously, she's back at work, she's not disabled anymore, and so that makes that clear. But if if you want to be more granular about this and zoom in a little more rather than taking the the very high-level views, the one year permanency date is the correct one. Q. In general? A. Yes.

Dr. Mandell's apportionment opinions lacked reasoning and were conclusory, failing to meet the burden of proof for apportionment.

Favours Applicant prevailed

AMERejected

Dr. Mandell's MMI opinion was inconsistent, ambiguous, and speculative, including the word 'probably' which made it less credible than Dr. Fletcher's unequivocal opinion. Dr. Mandell's apportionment opinions lacked reasoning and were conclusory, failing to meet the burden of proof for apportionment.

The Appeals Board found Dr. Mandell's MMI opinion inconsistent and speculative, and his apportionment opinions conclusory and lacking required reasoning, thus not substantial evidence.

From the decision · page 6Furthermore, the inconsistent, ambiguous and speculative characteristics of Dr. Mandell's MMI opinions are summarized in the following questions and answers during the 4/16/25 deposition. Page 15; 21 to page 16; 14: Q. Okay.

PTPRelied upon
