The network wants the judge to stop Gosselin from making media appearances that it says violate his contract as a star of the hit reality show "Jon & Kate Plus 8."
Gosselin has filed a countersuit, claiming TLC violated Pennsylvania's child labor laws in filming the show about the Pennsylvania family with eight children. His lawyer Mark Heller says there's no reason for the network to stop him from earning a living as a media personality, especially now that the show has ended amid the Gosselins' pending divorce.
But TLC, which is owned by Silver Spring, Md.-based Discovery Communications, says the contract remains in force.
TLC Chief Operating Officer Edward Sabin testified earlier that Gosselin made unauthorized appearances and endorsements. In particular, he mentioned a pool party that Gosselin hosted at the MGM Grand Hotel in Los Vegas. Sabin said photos that appeared afterward were at odds with the wholesome image of the show, "Jon & Kate Plus 8."
The judge is expected to rule sometime Thursday evening.
