A lawyer for TV3 accuses the Broadcasting Standards Authority of being out of step with society.
TV3 is to appeal in court against a BSA decision which criticised the channel for screening inappropriate images before the 6pm news.
Television New Zealand is also appealing against a ruling that said the use of the "f" word in a current affairs programme about the Aramoana massacre was inappropriate.
The word was used by a police officer when recounting events.
TV3 lawyer Clare Bradley says she can not understand why TVNZ was found to be in breach and is questioning the BSA's motives.
The BSA said the programme was broadcast at a time when children could be watching.
