In the period after the change in political regime, EZÚ had to resolve debts in its technical infrastructure accumulated in previous periods, which led to the refurbishment of the main building of the institute and to general modernization and the further development of its testing and measuring equipment. In the second half of the 1990’s, EZÚ successfully resisted restitution claims by various parties, including the existing Czech Electrotechnical Association – and established that all EZÚ assets are the property of the state. In 2000, the Supreme Court in Brno confirmed that ESČ is not the legal successor of the Czechoslovak Electrotechnical Association, finally rejecting all ESČ claims against EZÚ, both concerning real estate and the ESČ mark.
