In addition, he ran for Mayor in the 2011 local elections. He resigned from politics following his indictment and subsequent conviction for child sexual abuse. In 2011 Birkedal was charged with having sex with a minor and sexual misconduct.
He was also suspected of sexual offences against 13 boys.
Subsequently, Birkedal resigned from all political offices, effectively ending his political career. In February 2012 the city court acquitted him on the most serious charges involving sex with a minor, while he was convicted on lesser charges involving secret filming and inappropriate internet conduct, to which he pled guilty.
He was sentenced to 60 days in prison, of which 40 days were suspended. The non-suspended part of the sentence had already been served in custody.
The verdict was appealed by the public prosecutor.
On 17 October 2012 Birkedal was found guilty of sex with a minor and sentenced to 7 months in prison. He was fined to pay the victim 60,000 NOK in compensation by Gulating Court of Appeal. On 12 December 2012, the Supreme Court rejected his appeal of the conviction, and his conviction for sex with a minor is thus final.
But, the court agreed to hear the sentencing.
The Supreme Court rejected his appeal of the sentencing on 7 February 2013. Both the conviction and the sentence are now final.
