As cases challenging state marriage bans begin to pile up at the Supreme Court, there are signs that the justices are preparing to review at least one of them.

The first news came Tuesday night from influential blog SCOTUSBlog.

“Along with the two new filings [from Wisconsin and Indiana], the Court has awaiting it individual petitions on the issue from Oklahoma and Utah and three from Virginia,” Lyle Denniston wrote. “In all of the cases, both sides and a lengthening list of 'friends of the Court' have agreed that the Court should take on the constitutional controversy now. The Court may indicate as early as tomorrow which of the seven cases, if any, will be considered by the Justices at their first Conference of the new Term, on September 29.”

“The Court has the option of taking on either or both issues, and it also has the option of putting off any consideration for the time being, despite the heavy pressure from virtually everyone involved in the cases, who contend that the Court should not wait any longer to decide. None of the cases is a mandatory appeal. It would be highly unusual, however, for the Court to pass up all of the cases, when everyone is championing review now,” he added.

Further evidence of movement was found in a filing from Indiana asking the high court to stay a lower court's order striking down its ban pending Supreme Court action.

“The case is thus fully submitted to the [Supreme] Court on Petition for Writ of Certiorari, and Supreme Court personnel advise that the Petition will be before the Court at its first conference of the coming October term on September 29, 2014,” the brief states.

Dale Carpenter, a gay rights expert at the University of Minnesota law school, told the AP that he doesn't “see a lot of reasons for the [justices] to wait.”

“You have almost no one at this point opposed to certiorari,” he said.

Additional cases are also in the legal pipeline. Federal appeals courts have already heard arguments in cases challenging restrictive marriage bans in Hawaii, Nevada, Idaho, Tennessee, Kentucky, Michigan and Ohio.
