WCAC
LC No. 92-001000
Defendant-Appellant.

Before: Hoekstra, P.J., and Sawyer and T. P. Pickard*, JJ.
PER CURIAM.
Defendant appeals a May 12, 1995 decision of the Worker’s Compensation Appellate
Commission (WCAC) affirming an award of benefits for a heart disability. We reverse and remand.
In a decision mailed October 22, 1992, a worker’s compensation magistrate granted plaintiff an
open award of benefits based upon a December 21, 1989 work injury date, finding that plaintiff had
established a work-related cardiac disability per the standard incorporated into §§ 301(2) and
401(2)(b) of the Worker’s Disability Compensation Act in 1982. The magistrate did not have the
benefit of the Michigan Supreme Court’s decision in Farrington v Total Petroleum, Inc, 442 Mich
201; 501 NW2d 76 (1993), and in fact relied upon prior cases applying the pre-1982 common law
standard of causation in heart cases, i.e., Miklik v Michigan Special Machine Co, 415 Mich 364; 329
NW2d 713 (1982) and Kostamo v Marquette Iron Mining Co, 405 Mich 105; 274 NW2d 411
(1979).
In Farrington, supra at 216-217, the Michigan Supreme Court recognized that the “significant
manner” standard of §§ 301(2) and 401(2)(b) imposes a more stringent standard of proof than the
“mere causal relationship” standard of causation applied in Miklik and Kostamo. The claimant is not
only required to show some work-related contribution to or aggravation or acceleration of the disabling
heart condition, but also that the contribution, aggravation or acceleration from employment was
significant in comparison with all of the other factors affecting the development of the disability, including

relevant nonoccupational factors such as age, weight, diet, genetic predisposition and use of tobacco or
other drugs. Id. See also Gardner v Van Buren Public Schools, 445 Mich 23, 47; 517 NW2d 1
(1994).
In the instant case, the magistrate noted that there was evidence of several nonoccupational
factors affecting plaintiff’s cardiac condition, such as a long-standing smoking habit, preexisting
arteriosclerosis and a family history of heart disease. However, the magistrate’s only analysis of the
relative significance of those factors was that such “personal factors” were “not paramount enough to
preclude plaintiff from receiving benefits.”
The WCAC affirmed the magistrate’s decision in a 2-1 split decision. The WCAC majority
opined that the magistrate properly applied the “significant manner” standard as explained in
Farrington, and that the magistrate’s assessment of plaintiff’s nonoccupational factors as being “less
significant than” plaintiff’s work factors was not unreasonable. The dissent opined that the magistrate’s
analysis does not sufficiently comply with requirements of Farrington, especially since the magistrate
relied upon the lesser causation standard in Miklik, and therefore the dissent would have remanded the
case to the magistrate for a supplemental opinion in light of Farrington.
We agree with defendant and the WCAC dissent that the magistrate’s opinion is insufficient to
indicate that the magistrate engaged in the kind of analysis required by Farrington. An opinion is
inadequate for purposes of review when it is so conclusory or incomplete as to require speculation
regarding the facts and legal reasoning relied upon for the conclusions reached. Woody v Cello-Foil
Products (After Remand), 450 Mich 588, 597; 546 NW2d 226 (1996). See also Lombardi v
William Beaumont Hospital (On Remand), 199 Mich App 428, 436; 502 NW2d 736 (1993).
Here, the magistrate’s opinion contains no express reference to the “significant manner”
requirement whatsoever, and the magistrate’s determination that plaintiff’s nonoccupational factors were
“not paramount enough” is insufficient to unequivocally indicate even whether the magistrate found those
factors “less” significant than work factors, as the WCAC majority assumed. Arguably, if the
magistrate had found the nonoccupational factors less significant she would not have found them
“paramount” at all, as opposed to merely not “paramount enough.” The magistrate’s reliance upon
language from Miklik that was later characterized in Farrington as indicative of the lesser “mere causal
relationship” standard also renders the magistrate’s application of the statutory standard suspect.
In accordance with Woody, supra, we reverse the decision of the WCAC and remand the case
to the magistrate for further proceedings and detailed findings on whether plaintiff has satisfied the
requirements of the “significant manner” standard in light of Farrington, supra. Because we are
remanding the case for further proceedings before the magistrate, we do not reach defendant’s other
allegations of error.
Reversed and remanded. We do not retain jurisdiction.
