European courts have repeatedly said that in France the procureur (public prosecutor) isn’t an “independent judicial authority”.

The European Court of Human Rights has reminded this point (e.g. 29 Mar 2010, appl. no. 3394/03), and the Court of Justice of the European Union reaches a very similar conclusion (2 Mar 2021, C-746/18): prosecutors are part of the executive hierarchy and can’t be treated as the neutral, independent judicial check some procedures require.

For a local observer, this is made obvious by the fact that the procureur, in France, always follows current political vibes, usually in just a few months delay (extremely fast, when you consider how slowly justice works in the country).
