Magnus Matningsdal (born 29 September 1951 in Hå) is a Norwegian judge.
He graduated as cand.jur. in 1976 and then took the dr.juris degree in 1986. He was a professor at the University of Bergen from 1987 to 1989, and assisting professor from 1989 to 1997. At the same time he was a judge in Jæren from 1989 and presiding judge in Gulating from 1996 to 1997. He is a Supreme Court Justice from 1997.[1][2]
On 5 February 2008, the Standing Committee on Scrutiny and Constitutional Affairs of the Norwegian Parliament recommended that a commission be named to investigate and, if warranted, prosecute for impeachment three of the Norwegian Supreme Court Justices who presided over the cases of Fritz Moen, a victim of miscarriage of justice. The three were Matningsdal, Karin Maria Bruzelius and Eilert Stang Lund.[3] However, when the case was treated by the Standing Committee on Justice three months later, it was closed.[4]
