Bobby Sanchez resigned his seat in the state House of Representatives on Wednesday, hours after his inauguration as the mayor of New Britain.

Sanchez, a Democrat who has represented the 25th House District since 2011, was elected mayor last week, succeeding Republican Erin Stewart. The vacancy will be filled in a special election yet to be scheduled.

With a Democratic majority of 102-49, the loss of one Democrat will not appreciably change the balance of power in the House.

It will have a modest impact on the three-fifths vote necessary to pass legislation that temporarily diverts $500 million slated for the state’s pension fund to its budget reserves. Ninety votes now will be necessary for passage, not 91.

In establishing so-called fiscal guardrails in 2017 that, among other things, required surpluses generated by volatile sources go first to budget reserves, lawmakers imposed a “bond lock” that bars changes to the guardrails with less than a three-fifths vote.

Three fifths of 151, the number of House members without vacancies, is 90.6, which would be rounded up to 91. Three-fifths of 150 is 90.
