Croatia's Public Administration Minister Arsen Bauk said it was important that the two-day conference would discuss the right to access information law.
Parliament is in the process of appointing the first information commissioner and the law will contribute to the transparency of public administration bodies, he added.
Assistant Justice Minister Renata Duka said it was an outstanding honour that during its judicial reform for Croatia had had the assistance of French experts because France "is one of the leading countries in terms of administrative law and administrative science."
Constitutional Court Judge Mario Jelusic said the conference was an opportunity for Croatian and French experts to evaluate the latest experience in the new administrative judicature in Croatia, which he said was aimed at protecting citizens' rights and building the rule of law.
French Ambassador to Croatia Michele Boccoz, who attended as the French president's envoy, commended the Croatian judicial reform so far but added that commitments undertaken from the European Commission, referring to the European Arrest Warrant law, must be honoured.
The rector of Pantheon-Assas University, Guillaume Leyte, said France had a huge experience in administrative law.
Accession to the European Union raises many questions for Croatia that we have to discuss at this conference, which addresses a very important topic, changes in administrative judicature, he said.
Split University rector Ivan Pavic said French experts had contributed to the development of legal science in Croatia.
Jacques Biancarelli, a member of France's Council of State, said this year's Croatian-French Administrative Law Days were especially important because they were taking place for the first time since Croatia joined the EU on July 1.
