A U.S. judge has ruled in the dispute between Jon Gosselin and the TLC network that the father must stop making media appearances that are at odds with his contract.
Circuit Judge Michael D. Mason ruled Thursday following a one-day hearing.

TLC Chief Operating Officer Edward Sabin testified that Gosselin made unauthorized appearances and endorsements. In particular, he mentioned a pool party that Gosselin hosted at the MGM Grand Hotel in Las Vegas. Sabin says photos from the event were at odds with the wholesome image of the show, "Jon & Kate Plus 8."
Gosselin did not appear in court and his lawyers did not present any evidence.
The judge granted a preliminary injunction. A trial is scheduled for April 19.
