The Balance of Power
A distinct characteristic of the American Public Trust Doctrine is that federal
and state governments exercise concurrent authorities over Public Trust interests.

Courts examine the circumstances and purpose of any federal or state action
before applying the general principles of
- Supremacy
- Preemption
- Sovereign immunity
