Houston's firefighters pension fund sued Mayor Sylvester Turner and numerous city officials late Tuesday over the pension reform plan that passed the Legislature last week, arguing the landmark legislation is unconstitutional. The Houston Firefighters Relief and Retirement Fund argues the reform plan unlawfully undercuts the board's legal authority to "select legal counsel and an actuary and adopt sound actuarial assumptions" and seeks to have a court permanently block the city from acting as though the reforms will become law. Gov. Greg Abbott signed the bill into law Wednesday morning. Such an injunction presumably would extend to the city budget for the fiscal year that starts July 1, which City Council is scheduled to discuss Wednesday.
