Career
During his tenure as Prime Minister, Liechtenstein was involved in the process of European integration and experienced economic growth. However, it also faced problems in its foreign relations, such as a dispute with the Czech Republic in 1992 over the confiscation of Prince Hans-Adam’s estates in 1945 and a 2001 dispute with Germany over royal property confiscated in order to pay war debts.
After the end of his term as Prime Minister, Frick was involved in a political controversy surrounding the constitutional referendum in 2003, whereby it was proposed that the ruling Prince be given wider powers. Frick led the opposition to the proposed changes, which were subsequently approved by the electorate.
