Wait a damn minute. Remember how Bruce planned to reshape Gotham and then The Court of Owls sentenced him to die? Well Dick is doing the same thing in Bludhaven but on an even larger scale. You can't tell me the Owls wouldn't feel threatened by that.

BuT tHe OwLs aRe iN GoThAm. Baby, they're everywhere. Plus, Gotham and Bludhaven are both in New Jersey. Trust me, they would give a shit, especially when it concerns someone like Dick who double-crossed the Parliament of Owls and severely fucked them over.
