Under the legislation same sex couples in Maryland would have the same full marriage rights as heterosexuals.
The measure includes protections for religious groups and instiutions to keep them from being forced to particpate in gay weddings.
Earlier this week, the legislation was stalled in the House Judiciary Committee when it became apparent that supporters didn't have the votes needed to pass the measure.
Two Democrats, Delegates Jill Carter of Baltimore and Tiffany Alston of Prince George's County, forced the delay. The delegates were looking for more funding for Baltimore City and Prince George's County schools.
The legislation has already been approved by the state Senate, it now heads to the full House of Delegates.
