The law school at the University of California, Davis, is now a better fit for its 610 students. A $30 million new wing has been added to the school’s building, which was intended for only 50 students when it was first built in 1968. “We were, in effect, bursting at the seams,” Kevin R. Johnson, dean of the law school, said in a Friday interview. A ribbon-cutting event was held Friday for the new wing, which includes six new classrooms, one of which serves as a courtroom. The law school’s building gained 18,000 more square feet with the new addition. The new courtroom has room for 125 people and is more technologically up-to-date than the courtroom in the building’s old wing, said Pamel
