At present, Paris has more control over the Collectivité than the Hague has over Country St Maarten.

On the French side, there is also the Prefet (Prefect), who is an appointed French Government official. Some power and control still flows through the Prefet.

The French side also has Gendarmes, French Military Police with the responsibility for civil law enforcement. (The Marechausees are a similar Dutch force.) Gendarmes rotate in and out of the island periodically, just as many military units rotate through various posts.

So far, I've only seen the number of €62M in French recovery aid for St Martin. St Maarten may receive 8 or 9 times as much - if they can get their act together.
