DOJ told the Foreign Intelligence Surveillance Court in December that it now thinks "there was insufficient predication to establish probable cause" to substantiate two of its four applications to wiretap ex-Trump aide Carter Page. 
Judge Boasberg says in a newly-declassified order that DOJ has "concluded, in view of the material misstatements and omissions, that the Court's authorizations in [two Page FISAs] were not valid." DOJ didn't take a position on whether the other two were lawful.
The FISC ordered the government to produce a bunch of additional information, including how it will wall off whatever info it gained from the Page wiretaps, and to explain what "related investigations" that might be going on about those FISA applications.
This is a big deal. The Justice Department is conceding that two of the four FISA applications it used to conduct surveillance of former Trump campaign aide Carter Page were not lawful, and it's not defending the legality of its other two applications.
