Notes:

1. new poster means it is a good idea to search the ProZ glossaries first, though I could track down only English-Arabic entries, as in both weblinks, but may help the asker in Algeria. Alas, my knowledge of spoken-only Arabic is limited, so I can't tell.

2. Crown Action - often brought by UK Crown Agents overseas - to me intuitively denotes native land disputes in British Commonwealth countries like Canada, Australia and New zealand (cut to the Maori Waitingi Treaties and compensation against the British Crown going through the courts when I had been 'Down Under' in 1996).

3. The Crown Office in the Inner Temple, London, also deals with judicial review of administrative *UK* action: IATE website contrôle juridictionnel

PS 'En droit canadien, le ministère public (State / Crown Counsel's Office, Council of Europe FRE/ENG Glossary, FHS Bridge) est le poursuivant devant une juridiction pénale. Il est souvent appelé « la Couronne » car la fonction de poursuivant relève du pouvoir exécutif, lequel est représenté symboliquement par la Couronne dans les monarchies constitutionnelles' fr.wikipedia.org/wiki/Ministère_public
