The hearings for four different cases will come after the highest court’s refusal to review five circuit court decisions overturning same-sex marriage bans in October.
In two and a half hours of oral arguments, the court could determine the legality — according to the 14th amendment — of states denying same-sex marriage licenses, as well as whether the marriages will be recognized in states where it is not legal.
The court’s decision is likely to come in June, and Steve Sanders, a law professor at Indiana University and co-author of the Human Rights Campaign’s amicus brief, said he expects the court will rule against gay marriage bans.
“The most likely result is a 5-4 decision in favor of marriage equality with Justice Kennedy writing the majority opinion,” Sanders said.
This is not the first time the court has dealt with a definition of marriage — it has struck down restrictions in three different cases, he said.
“The idea that the Supreme Court doesn’t have any authority with the question of marriage is frankly just idiotic,” he said.
Despite the persistence of religious arguments for and against marriage bans, Sanders said he doubts they will be a primary focus.
“They’ll make arguments that are religious but intended to sound secular,” he said.
