MADISON, WI (WTAQ) - The Wisconsin Supreme Court said Friday morning it would not re-consider its decision from last year which upheld the state’s limits on most public union bargaining.

Dane County District Attorney Ismael Ozanne asked the justices to revisit the case without Justice Michael Gableman, because he got free legal help from a law firm that was involved in the matter.

Ozanne said Gableman should have recused himself, because the firm of Michael Best and Friedrich was involved in defending the union law. That’s the same firm who represented Gableman in an ethics case in 2010, and never billed him for its services.

Ozanne lost a legal challenge to the bargaining limits just over a year ago – and without Gableman’s vote, the union law would most likely be struck down in a deadlock.

Gableman’s three conservative colleagues agreed that the union law challenge should not be re-opened – but the other 3 justices went the other way.

The vote was the same as one from Thursday, in which the court refused to hold a hearing on whether Gableman should have recused himself from a case involving a Rock County livestock farm because Michael Best was one of the parties in the matter.
