Very interesting discussion, since the info we can gather about Marines privilleges over Shichibukai contradict themselves in my opinion. Gonna gather the points that stated in the posts below and add some more.

Marines can revoke Shichibukai


 * Tashigi (under Captain Smoker's command) removed Crocodiles privilleges in Alabasta


 * Issho (under Sakazuki's command) revoked Law's title in Dressrosa

Marines cannot revoke Shichibukai


 * Shichibukai are working under World Goverment and not under Marines


 * Issho could not revoke Doffy's title without having solid proves


 * In the Mariejois Meeting after Jaya's arc the Gorousei would decide who's going to take Crocodiles place in the Shichibukai. Even if Shichibukai and Marine Officers were there, we can safely assume that their role was consultive and not decisive.


 * Smoker had the reason to revoke Law from Shichibukai during Punk Hazard, although he didn't seem to have the permission


 * What gonna happen with Doffy's case was totally in the hands of World Goverment. Not only Marines kept a passive stance during their meeting in Mariejois, but they also got tricked and and they could do nothing about it.

My conclusion

Seems to me that Marines cannot decide if a Shichibukai gonna stay or not. As long as a Shichibukai is acting like a Shichibukai they can do nothing. They are just allies and they don't hold any privillege on them.

In some special cases, the Marines have solid proves that a Shichibukai is acting against the rules. In these cases they can capture him as a simple pirate and drop him in front of World Goverment. It would be really inefficient if they should let him escape and after the report they have to find him again ;)

In total we have three of these cases. 1) Captain Smoker captured Crocodile since his illegal activities were revealed. This action, as long as the obligation to keep his mouth shut, rewarded him the rank of Commodore. 2) He fought Law and he could capture him if he had the possibility during Punk Hazard arc. Even if he was a Shichibukai his actions was enough to revoke his title. 3) Issho knows very well during this arc that Law's alliance with Luffy is enough to revoke him from his title, so he can attack him as a normal pirate.
