From the NYTimes:

The Wisconsin Supreme Court on Wednesday effectively handed the Republican-controlled State Senate broad authority over the composition of state boards and commissions, three and a half years into the term of a Democratic governor whose duties include naming board members.

The ruling allows a Republican member of the state Natural Resources Board whose term expired in May 2021, Frederick Prehn, to keep his position. Dr. Prehn had refused to step down, arguing that a replacement to his post has not been confirmed.

The court’s 4-3 opinion, which fell along partisan lines, turned on a technical question of when the seat on the board would be legally vacant. But its practical effect was to affirm a strategy devised by the State Senate to keep Republican board members in office simply by refusing to confirm replacements nominated by Gov. Tony Evers, a Democrat.
