After a minor court hearing yesterday morning, Yale history professor Paul Kennedy’s trial was postponed until May 15.

No legal representatives for Kennedy appeared in court for the hearing, which officials from the Court Clerk’s office called purely administrative. Kennedy faces five charges, including driving under the influence of drugs or alcohol, for his involvement in a Feb. 2 car accident in which a School of Music student was injured.

Following Kennedy’s arrest, both Yale administrators and Kennedy’s colleagues told the News that Kennedy was sober at the time of the accident. Kennedy’s lawyer, Greg Pepe, said New Haven Police Department officers likely mistook Kennedy as intoxicated because of injuries he sustained from polio as a child. Kennedy, he said, has a slightly crooked walk and is unable to pass field sobriety tests.

Kennedy’s vehicle struck Marisa Green MUS ’06 as she was exiting her parked car on Bishop Street. Green sustained minor injuries.
