DALLAS — Mark Cuban is suing the Securities and Exchange Commission for access to documents detailing the insider trading case against the Dallas Mavericks owner.

The Dallas billionaire filed requests for records in December under the Freedom of Information Act. That was a month after the SEC sued Cuban, accusing him of selling shares of Internet search engine company Mamma.com after receiving confidential information about a private offering.

Cuban's lawsuit claims the SEC improperly rejected some requests, didn't respond quickly enough to appeals of rejections and failed to conduct adequate searches for some records.

Cuban provided a copy of his lawsuit to The Associated Press after it was reported by The Dallas Morning News. An SEC spokesman declined comment.
