The correct path would have been to file a law suit in federal court against ICE and the Obama Administration for failing to enforce immigration laws with due diligence.

I think you're probably correct.

I believe another even farther reaching suit would be to sue the Obama Administration for selective enforcement of the law. In effect negating by fiat laws that have been enacted in accordance with the Constitution and thus demonstrating an unwillingness to perform his constitutionally assigned duties as chief law enforcement agent.
