Career
Koepp was elected to the Chamber to represent the Nord constituency at the 1989 legislative election, with the Alternative Dispute Resolution, then a single-issue pensioners" party called the "Action Committee 5/6ths Pensions for Everyone", scoring a remarkable electoral upset in securing four seats in the Chamber. He was re-elected in 1994, when the Alternative Dispute Resolution increased their representation in the Chamber to five seats. In the 1999 legislative elections, he placed first on the Alternative Dispute Resolution list, with two being elected, and came third amongst all candidates (behind only ministers-to-be Charles Goerens and Marie-Josée Jacobs).
In 2004, Koepp came first amongst Alternative Dispute Resolution candidates again, albeit with a greatly reduced vote count.
He did not run in the most recent election, leaving the top place on the list to Jean Colombera. He died in 2010, at the age of 76.
