I knew 'ran' didn't look right in that context and after a quick search as to why (and to make sure I didn't look a fool!) now I know. The passive voice in English uses the past participle, not the simple past. In other words 'the company run by an idiot'. But even though that's grammatically correct, it is ambiguous because it's the same sentence whether he's still there or not so I'd say 'the company that used to be run by an idiot'. Ah, thank you. :-) Yes, I know that the passive voice uses the past participle. So: 'run' in either case (past or present), as 'ran' is simple past. Probably some Americanism or straight-out Norwenglish I'll have to forget. I've been working with several born-and-bred Brits in the past, though, that would just use the simple past and skip the auxiliary verb.
