Monday is Crossover Day, one of the most crucial days of every legislative session under the Gold Dome.

By the 30th day of the 40-day session, bills must win approval in one chamber or the other of the Legislature – or cross over, per se – to have a good chance of becoming law. There are ways for bills that don’t cross over to later win approval, but it’s not so easy and takes parliamentary maneuvering.

Some major bills of this session have already crossed the threshold from one chamber to another. They include House Bill 757, the primary “religious liberty” bill of this session; House Bill 859, the campus carry bill; and House Bill 927, which would expand the state’s Supreme Court.

Leading bills that still face Monday’s deadline include House Bill 677, which would allow for up to four destination casinos in Georgia; House Bill 722, which would expand the list of diseases and conditions that could be treated with medical marijuana; and Senate Resolution 756, which would reduce the state’s 6 percent maximum income tax rate.
