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.
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.
