Clear Terms

Search Primer

Term list: Separate terms with spaces, not commas or semicolons.

Multi-word term: Place inside quotes to ensure an exact match (e.g. "China import").

Acronyms: Use all capital letters to ensure the search is not looking for that letter sequence instead.

Required term: If a term must be included in any resulting articles, prefix it with a plus sign (e.g., +CBP).

Excluded term: If a term should be excluded from any articles being found, prefix it with a minus sign (e.g., -ruling).

Singular form: Always use the singular form when doing multi-word terms (e.g. "russian export control" instead of "russian export controls").

Shortest word form: When you have different word forms in a quoted (multi-word) term, you want to only include the shortest version if it is the last part of the expression (e.g., "entity list" instead of "entity listing" or "entity listed").

US Tells 9th Circuit Transfer Order Unreviewable in Blackfeet Nation Members' Tariff Suit
December 9, 2025 by Jacob Kopnick|Litigation

The U.S. filed a supplemental brief on Dec. 3 urging the U.S. Court of Appeals for the 9th Circuit to affirm a Montana court's decision to transfer a group of tribal members' tariff lawsuit to the Court of International Trade. The government said the plaintiffs will be able to fully adjudicate their claims at the trade court and that the 9th Circuit can't review the Montana court's transfer order, since it's not a final order nor an "immediately appealable collateral order" (Susan Webber v. U.S. Department of Homeland Security, 9th Cir. # 25-2717).
