I am wondering if you mean the inversion of subject and verb in direct speech like in :
Il a décidé de quitter le pays , parait-il. = He has decided to leave the country, it seems ( apparently).
In these cases, no, they are not questions that would always have a question mark at the end.
Let me know if this is what you had in mind.
Not sure what you mean?
May I ask you to give a couple of examples, then it may be possible for a contributor to comment constructively?
Merci et bonne journée
