Interesting Words - Gainful Employment

In legalese, "gainful employment" is defined as work that a person can pursue and perform for money or activities intended to provide an income to a person.

(This is where wording can have a huge effect, as Tony Hakki, a professional poker player, who allegedly refused to pay child support for his children, has won a legal fight to keep all his poker winnings.  Court of Appeal judges agreed that Tony Hakki's winnings were not from "gainful employment" and so did not meet the regulations governing the payment of child support.

This is what I would call "getting off on a technicality".)
