Is there intent to use UN Security Council resolutions on terrorism as an international legal basis for PSI actions?
The PSI SOP states that activities will be undertaken consistent with national legal authorities and relevant international law and frameworks. If an activity is authorized under a UNSC resolution, then it could be cited by a PSI participant as authority for its participation in an interdiction. Participation in the PSI is voluntary. If a state believes it does not have the legal authorities to act in a specific action, it can decline to participate.
