The state House Judiciary and Finance committees are holding a public hearing Thursday on the marriage equality bill passed by the full Senate Wednesday. The hearing is expected to last until at least midnight. Meanwhile, Representative Bob McDermott announced yesterday that he filed a legal challenge in Circuit Court, arguing that only another constitutional amendment can change the 1998 constitutional amendment that gave the Legislature the power to define marriage between a man and a woman. The lawsuit, which names Governor Neil Abercrombie and House and Senate leaders, asks the court to declare any gay marriage bill passed during the special session null and void.
