Well I'm pretty confused after having read some recent threads. As I understand it, most ID's (the ones that don't say "May treat as combat target") are subject to:
Quote:6.6 Aggressors are not allowed to destroy a trade vessel prior to issuing a demand, in system or local chat, and allowing sufficient time to respond. Demands may be cargo, credits or an RP demand, such as leaving the system. "Halt" is not a demand. You must say more than this to ask a ship to stop however you may destroy them if they attempt escape.
And that's sort of independent of the general affiliation between your ID and his, say if it was a BAF'er he'd be subject to 6.6 too (because there's no "May treat as combat targets" on the BAF ID even though Bretonia is at war with Gallia, and therefore also IDF). But I could be wrong, there's some discussions about demanding duels and whatnot, and I'm confused.
It's hard to say without info on the other dude's ID, but if he was a Maquis for instance and you were in Gallia I'd wager it would be fine because of:
Quote:Pilot carrying this ID is a member of the Maquis who:
May treat all trade vessels in Gallia as combat targets.
