A recent landmark court ruling in favor of a porn actress desperate to quit the industry paves the way for others to cut ties with the world of commercial sex without fear of penalties, lawyers said Tuesday.

They said the ruling also deals a blow to the county's largely unsupervised porn video business.

In what the lawyers say is the first legal case of its kind, the Tokyo District Court in early September dismissed a lawsuit filed by a porn production company against a woman in her 20s in which it claimed more than ¥24 million in damages after she suddenly declared she would end her contract.
