Finally, it is clear that, while comparative examination of the Member States’ legal systems enabled the Court to make at a very early stage the finding recalled in paragraph 170 of the present judgment concerning convergence of those legal systems in the establishment of a principle of liability in the case of unlawful action or an unlawful omission of the authority, including of a legislative nature, that is in no way the position as regards the possible existence of a principle of liability in the case of a lawful act or omission of the public authorities, in particular where it is of a legislative nature.
I denne henseende skal det endelig konstateres, at mens en sammenlignende gennemgang af medlemsstaternes retsordener gjorde det muligt for Domstolen på et meget tidligt tidspunkt at foretage den i denne doms præmis 170 anførte konstatering for så vidt angår den omstændighed, at der i disse retsordener er et sammenfaldende princip om erstatningsansvar i tilfælde af en myndigheds ulovlige handling eller undladelse, herunder vedrørende generelle retsakter, gælder det samme ikke for så vidt angår et eventuelt princip om erstatningsansvar i tilfælde af en offentlig myndigheds lovlige handling eller undtagelse, navnlig når de vedrører generelle retsakter.
