I can't divulge the details in full, but it's an FOI request where legal advice was obtained from an external law firm. The agency has noted that they had 'ongoing relationship' with this firm. That suggests ongoing business and the possibility that they may have been employed in other capacities other than a legal capacity. As is the rule under common law for in-house counsel I would think that there is a need to prove that the agency did not employ this law firm in, say, a commercial capacity as well.
I can find plenty of case law where this rule has applied to in-house lawyers but not for external law firms.
This is why I was hoping to find some case law that would support an arguement for scrutiny of this external law firms relationship with the agency. This way I can argue to counter their claims of legal professional privilege.
Thanks for your help.
