Colin Baker (in-universe)

Information from invalid sources
Colin Baker was an actor from BBC's Doctor Who who was put on trial twice.

Biography
At some point in Baker's life, he had been put on trial. He was later put on trial once again, this time for an unpaid parking fine, which he received whilst filming new bonus material for the Doctor Who Season 23 Blu-Ray Collection. During the trial, he tried to justify to the magistrate that he should be excused, and that the very fact he was on trial was a farce. Baker also provided evidence downloaded from the Time Lord's Matrix, but to no avail, and he was placed in a cell with a female friend. (NOTVALID: The Sixth Doctor is on trial AGAIN!)
