Washington (CNN) The typically ultra-close-lipped Foreign Intelligence Surveillance Court slammed the FBI for mistakes it made in the Carter Page surveillance warrants and ordered the agency to detail how it will improve its warrant applications in light of the errors, uncovered recently by the Justice Department's inspector general.

The order is a startling departure from the court's typical comprehensive secrecy as it reviews from federal investigators requests for warrants related to foreign intelligence.

The public statement on Tuesday from its presiding judge appears to nod to growing criticism that the warrant-application process has become lax or lacks transparency. Groups such as the American Civil Liberties Union have sought more public disclosure of the court's actions to prevent the abuse of Americans' rights for years, and Sen. Lindsey Graham, a South Carolina Republican, last week said he believed the court should be reformed in light of the inspector general report.

"The FBI's handling of the Carter Page applications, as portrayed in the [Office of the inspector general] report, was antithetical to the heightened duty of candor described above. The frequency with which representations made by FBI personnel turned out to be unsupported or contradicted by information in their possession, and with which they withheld information detrimental to their case, calls into question whether information contained in other FBI applications is reliable," federal Judge Rosemary Collyer wrote in an order from the court published Tuesday.

The FBI has until January 10 to respond. It's unknown at this time if that response will be made public, since correspondence with the court is often classified.
