Gallen was challenged by NRL Counsel Peter Kite that the contact with his knee and Taylor's head was forceful and that he had a duty of care to avoid it.
The workhorse lock was a little prickly in arguing his innocence, but jokingly denied afterwards that he has a future as a defence lawyer.
"I don't know if I could handle all the uni degrees," he said.
Gallen can now enter into the State of Origin period without the burden of carry-over-points and, even though he's believed to be in reasonable doubt for Sunday's match, he said it was still a risk to fight the one-match ban.
The 30-year-old said he was hopeful of facing the Storm.
"I had a light training session today and I'm doing everything I can to play," he said.
"Shane (Coach Flanagan) will give me up until game day. It's a massive game for myself and the club."
Gallen said Flanagan came out of Wednesday morning surgery for a twisted bowel well and is on the road to recovery.
"He wants to come back to work tomorrow but we'll give him the week off I reckon," Gallen said
