The University of Nebraska’s Board of Regents ran afoul of a state open-meetings law when it gave little notice before voting to oppose a controversial ballot measure on affirmative action, the state’s attorney general, Jon Bruning, has concluded.

In a letter announcing his finding, Mr. Bruning also said, however, that the board had “cured” the violation by putting the resolution up to a vote a second time in a very public manner. Instead of reprimanding the board, his letter cautioned it to be specific in future meeting announcements.

The agenda for the board’s January 18 meeting had said only that it would be taking up “kudos and resolutions” when it passed a resolution opposing, and urging Nebraskans not to sign, a proposed ballot measure barring public colleges and other state agencies from using affirmative-action preferences.

After a supporter of the ballot proposal challenged the board’s action as a violation of the state’s open-meetings law, the regents took up the resolution again at their March 7 meeting, giving a detailed public notice of their intent. After soliciting comment, they adopted the measure once again. —Peter Schmidt
