Advocates for same-sex marriage in Colorado went to federal district court Friday seeking to immediately lift a court stay on the marriage ceremonies.
On July 9, an Adams County District Court judge ruled the state's same-sex marriage ban unconstitutional, but stayed the ruling pending appeals.
Colorado Attorney General John Suthers has stated he will defend the ban.
But in a motion in federal district court, the ban's challengers argued there is "no compelling or convincing reason to delay" in allowing same-sex marriages.
In the motion, the challengers said Denver, Boulder County and Pueblo have all started issuing marriage licenses, and this in no way has hurt the citizens of Colorado.
"The world as we know it has not crumbled," the motion said.
The motion also argues that based on rulings in other states, there is little likelihood of the appeal being successful.
"Colorado Attorney General John Suthers' fight against equal rights is a lost battle," Mari Newman, an attorney representing the group, said in a statement.
"It is time for Attorney General John Suthers to quit standing in the way of marriage equality in Colorado," Newman said.
