RALEIGH, N.C. (AP) – Gov. Pat McCrory says a pending lawsuit over North Carolina executive and legislative powers is why he is letting a bill responding to current and past court rulings become law without his signature.

McCrory announced his decision on Sunday, the constitutional deadline to act.

The General Assembly passed the bill making it optional for McCrory to order more conflict-of-interest requirements for people who serve on a coal ash commission and two other environmental panels

A law last year that McCrory has challenged in court mandated those requirements and also gave legislative leaders the ability to appoint positions to some executive branch commissions. The state Supreme Court will hear McCrory’s legal challenge June 30.

The bill at McCrory’s desk also removed longstanding requirements that actual legislators serve on three other panels.
