But unbeknownst to German authorities, the teacher took up a post at a private business school in Bern, Switzerland in 2001, where he taught law for a monthly pre-tax salary of 12,000 Swiss francs, or €9,900.
Bild reported that he continued to take a state pension benefits up to €2,000 a month until 2004, when the Hesse state learned of his lucrative Swiss job.
Despite this, he continued to claim his private occupational disability insurance of €988 a month, even though a Federal Administrative Court ruled he was fit to work in 2010.
The court confirmed an earlier verdict, sentencing Martin B. to a suspended sentence of one year and a €20,000 fine. He remained silent throughout the case, but his lawyer said his client intends to appeal to a higher regional court.
He has since been sacked without notice by the Bern school, and faces a claim for €90,000 from his private insurer. But he does have something to fall back on - he is entitled to €4,000 a month of Swiss unemployment benefit for up to two and a half years.
