State Rep. Thomas Murt questioned the permits last week, saying Pennsylvania law allows children under 7 to work in movies, but not TV. Gosselin's sextuplets are 6 years old. Labor officials said Tuesday that the permits protect the children from working too many hours and ensure they receive earnings from the TLC show.
Murt maintains the permits are illegal. He says the labor department must seek a ruling from the attorney general.
Murt sent a series of letters to the state attorney general and labor secretary that questioned the legality of the work permits.
State labor officials previously said that TLC producers should have obtained work permits for the original 'Jon & Kate Plus 8,' though no penalties were made.
