On Wednesday, the trial began where Besseberg's appeal will be handled. It was a year ago that the now 79-year-old Norwegian was sentenced to three years and one month in prison for gross corruption.
Besseberg himself denies any crime. The first prosecutor, Marianne Djupesland, takes the opposite line.
We believe that we can prove that Besseberg used his position in IBU to benefit himself, she says.
The allegations previously directed against Besseberg concern that he allegedly received, among other things, hunting trips, prostitutes, and watches as gifts from Russia during his last nine years in office.
This is not a borderline case of corruption, but it is clear corruption, says Djupesland.
Besseberg himself will speak in court on Thursday and Friday. The entire trial is expected to last until May 20.
