Gov. Andrew Cuomo on Tuesday morning officially called for a special session of the Legislature to extend mayoral control of New York City schools.

In his proclamation calling for a special session, Cuomo also left the door open to “other subjects as I may recommend.”

“The Governor is calling an extraordinary legislative session for Wednesday, June 28 to take up the issue of Mayoral Control,” said Melissa DeRosa, the governor’s secretary and top aide. “The Governor has discussed the extraordinary session with the legislative leaders.”

It’s possible lawmakers will also consider a measure to bolster pension benefits for New York City police and firefighter unions as well as an extension of local sales tax measures.

Mayoral control is due to expire at the end of the month and the governor last week criticized the Legislature for failing to reach an agreement as a “dereliction of duty.”

A special session is a rare occurrence in Albany under Cuomo. The last one was held in 2011, when lawmakers and Cuomo agreed on revised tax rates as they were due to expire for upper income New Yorkers. At the time, Cuomo did not formally call a special session, but struck a three-way agreement to bring the Legislature back to the Capitol.

Lawmakers are not required by law to act, but gavel in for a session.
