SOMERVILLE TEACHERS ASSOCIATION vs. SCHOOL COMMITTEE OF SOMERVILLE.

When a Somerville teacher applied for family-plan health insurance coverage through a health care (or "health maintenance") organization (HMO) provided by his employer under G. L. c. 32B, Section 16, the defendant (school committee) refused to allow him anything more than individual HMO coverage because his wife, who was also a Somerville employee, was already covered for family-plan, indemnity-type health insurance coverage provided under G. L. c. 32B, Section 5. The school committee's refusal was based on the third paragraph of Section 16, which states in part: "All persons eligible for the insurance provided under [Section 5] shall have the option to be insured for the services of [an HMO] under this section but shall not be insured for both." G. L. c. 32B, Section 16, as inserted by St. 1971, c. 946, Section 5. The plaintiff (teachers' association) sought arbitration, claiming that the teacher was entitled under the collective bargaining agreement to the refused coverage. The arbitrator, however, agreed with the school committee that the statute prohibited coverage of the same family under both indemnity-type and HMO-type family plans. The teachers' association appeals from a judgment confirming the arbitrator's award.

On general principles a court usually will not review an arbitrator's decision for most errors either of fact or of law. Concerned Minority Educators of Worcester v. School Comm. of Worcester, 392 Mass. 184, 187-188 (1984), and cases cited. Everett v. Teamsters Local 380, 18 Mass. App. Ct. 137, 139 (1984). There may be some question as to the applicability of the general principles where the arbitrator's decision is based, as it is here, solely on what the arbitrator determines to be the overriding effect of a statute. See Alexander v. Gardner-Denver Co., 415 U.S. 36, 56-57 (1974); School Comm. of Hanover v. Curry, 3 Mass. App. Ct. 151, 156 (1975); Blue Hills Regional Dist. Sch. Comm. v. Flight, 10 Mass. App. Ct. 459, 467-468 (1980), S.C. 383 Mass. 642 (1981). In any event, we think the arbitrator's interpretation of Section 16 was correct. The teacher's election of family-plan HMO coverage would result in coverage of his wife (as well as any children) under both the indemnity plan and the HMO plan in violation of the plain terms of the statute. [Note 1] The statutory purpose of preventing the HMO option from creating additional costs for the governmental employer is evident throughout Section 16, [Note 2] see Hemman v. Harvard Community

Health Plan Inc., 18 Mass. App. Ct. 70, 73 (1984); and that purpose would be defeated if governmental employees who are part of the same family unit were exempted from the proscription against double coverage. Compare 805 Code Mass. Regs. 9.12 (1981), specifically precluding Commonwealth employees who are husband and wife from electing separate family coverages as part of their employee benefits.

As Section 16 is not one of the statutes enumerated in G. L. c. 150E, Section 7 (d), its mandate would override any contrary provision in the collective bargaining agreement. School Comm. of Holyoke v. Duprey, 8 Mass. App. Ct. 58, 63-64 (1979). National Assn. of Govt. Employees Local R1-162 v. Labor Relations Commn., 17 Mass. App. Ct. 542, 544 (1984).

Judgment affirmed.
