The 49ers are having quite a new year. On the first day of 2017, the club said adios to coach Chip Kelly and general manager Trent Baalke. A day later, team CEO Jed York practically roasted himself at a news conference by declaring that owners don’t get fired. On Tuesday, the 49ers sued the city of Santa Clara and its mayor, Lisa Gillmor, for breach of contract over Levi’s Stadium. Gillmor has accused the team’s management companies of hiding financial information from the Stadium Authority board, which she chairs. Back in early December, the city had its interim city manager, Rajeev Batra, send the club a notice that it could find itself in default of the stadium management agreement unless it turned over all documents. 49ers General Counsel Hannah Gordon fired back a day later, noting that everything had already been provided in a Nov. 18 meeting at the stadium and also included a 15-day estoppel certificate that demanded the city verify the club was playing by the rules on stadium management or present evidence to the contrary. Batra punted in a Dec. 20 letter, saying he couldn’t sign anything until all docs were presented but would be happy to meet. When Gordon responded in an email with available dates, city officials clammed up and took off for the holidays. Santa Clara appears to be in a tough legal spot, which will only get more difficult considering longtime City Attorney Ren Nosky put in his letter of resignation Dec. 30. He’s often the only person who takes notes in meetings with the 49ers, meaning all record of city-team interactions could soon be lost. Word is Nosky’s moving on to the law firm Berliner Cohen LLP, which specializes in land use and municipal law. The 49ers had no official comment on the lawsuit but it appears the decision to sue was made not by York but 49ers team president Al Guido, who oversees all business decisions. Perhaps that’s why the club’s chances of winning look decidedly better.
