Primary Legal Authorities and Sources

Frequently Asked Questions

What is the Garcia-Flores test?
The respondent generally must show that the violated regulation was intended to benefit the respondent and that the violation prejudiced the protected interest.
Is prejudice always required?
It is the general rule, although Garcia-Flores recognizes limited settings in which prejudice may be presumed.
Does every violation of a DHS regulation require suppression?
No. The purpose of the regulation, the protected interest, prejudice, and the connection to the evidence all matter.
Why does the encounter date matter?
Regulations and controlling interpretations change. The motion should use the version and precedent applicable when the challenged conduct occurred.
Can a regulatory claim overlap with a constitutional claim?
Yes. The same interrogation or arrest facts can sometimes support both theories, but each should be analyzed under its own legal test.
What evidence best proves prejudice?
A chronology showing what evidence DHS had before and after the violation, together with proof of the procedural safeguard lost, can be especially important.
