Although not all spouses were financial dependents, the court did not consider it unreasonable to assume they would nonetheless be embraced in the definition. It was such a longstanding practice that spouses would be covered under benefit plans that the General Assembly must have contemplated it. Otherwise, the court reasoned that "dependent" must include some kind of financial dependency rather than mere "financial interdependence". Based on its reading of the statutes and the attorney general's opinion, the court accordingly affirmed the circuit court's invalidation of the County's benefit plan.
