Wisconsin Statute §19.87(2) states “No provision of this subchapter which conflicts with a rule of the senate or assembly or joint rule of the legislature shall apply to a meeting conducted in compliance with such rule.”

In other words, if there is a conflict between the Open Meetings Law and legislative rules, the legislative rules prevail. Moreover, the Wisconsin Constitution grants the legislature broad authority in carrying out its business in Article IV, §8 where it states, in part, that “[e]ach house may determine the rules of its own proceedings.”

The rules of the Senate were unanimously approved by Republicans and Democrats in January.  Furthermore, Rob Marchant, the Senate Chief Clerk issued this statement about the Senate Rules on March 11:

"There was some discussion today about the notice provided for the legislature's conference committee.  In special session, under Senate Rule 93, no advance notice is required other than posting on the legislative bulletin board.  Despite this rule, it was decided to provide a 2 hour notice by posting on the bulletin board.  My staff, as a courtesy, emailed a copy of the notice to all legislative offices at 4:10, which gave the impression that the notice may have been slightly less than 2 hours.  Either way, the notice appears to have satisfied the requirements of the rules and statutes."
