Eligibility for retiree medical benefits requires that retiree have 15 years of service after age 47. An employee who retired early under Pension plan, but did not have the required 15 years of service after age 47, was inadvertantly enrolled in the retiree health plan. Can the plan stop providing benefits to this individual?

WHAT DOES THE PLAN SAY?

In general, an individual as you described could be removed from the plan, although you should review your plan document and the underlying policy. In addition, you may want to think about how you will handle the fact that if this individual terminated employment awhile back, s/he is probably no longer eligible for COBRA.
