Prescisely. It's the reason why the Federation wasn't allowed to support Gowron's petition to lead the High Council in 2367. Starfleet considered the matter "an internal affair of the Klingon Empire," so Picard wasn't allowed to intervene once his duties as Arbiter of Succession were finished.
He was allowed to stop the Romulans from shipping supplies to the Duras sisters because they were interfering in Klingon politics, but that was as far as Starfleet allowed him to go.
Privately, I think the PD is largely up to interpretation. The whole fact Starfleet wouldn't support Bajor against the Cardassians seems like [insert expletive].
