((I've been thinking over this for a few days, take the following IC or OOC i dont mind ))
Omni-Tek has the lease for Rubi-Ka for 'x' more years.
The ICC has deregulated some areas off Rubi-Ka for anyone to start their own mining facility. So apart from these plots OT still has the lease to everywhere else on RK, in fact without the Tir accord they can lay legal claim to all the clan lands ie the entire planet is Omni's except for those regions designated by the ICC to be 'free for all'.
Would taking that non-designated land for your own put you in conflict with OT? well as they are the legal holders then legally yes. The exception being the areas open for mining which anyone can legally hold.
Holding that land does not put you in the conflict as it is your right, granted by the ICC to hold the designated areas and to defend them as best you can, doing so doesnt make you a part of the war. Should you go on the offensive i feel that is a different matter and you should accept the consequences of your actions. Attacking a clan base doesnt make you an employee or ally of OT but it sure as heck makes you an enemy of that clan and their allies, the same applies for attacking OT.
However as wars are fought over and using strategic resources any mine is liable to be attacked by one of the big two players (OT or clan), but being attacked doesnt make you a side or ally you with any side.
The Newland treaty allowing neutral/independent or whatever to defend themselves is a good thing and only a natural reaction to events. Most neutrals groups (there ARE exceptions IMHO) simply want to 'live and work' on Rubi-Ka and almost all have a legal right to do so, they are legally under omni/ICC protection and juristiction. Given the recent events I dont blame legal neutral groups for wanting to defend their interests as best they can. should neutral group(s) go to war against one side or the other it is their business with that side and, dependent on their reasons eg attacking clans under an agreement with OT, does not make them a part of the OT/Clan conflict.
I also believe there are some neutral groups, naming no names, who are trying to get involved in the conflict in one way or another and i think the members of those orgs should do some soul searching.
