Why It Matters
A redistricting dispute centered on eastern Washington’s Yakima Valley could reshape how states across the country draw legislative maps — and how courts weigh race as a factor in that process. With the U.S. Supreme Court’s recent ruling tightening limits on race-based redistricting, Washington state’s request to revisit the case could have implications well beyond the 15th Legislative District at the heart of the controversy.
What Happened
Washington Attorney General Nick Brown filed a 19-page brief asking the U.S. Supreme Court to accept a redistricting challenge and send it back to a lower court for reconsideration under a new high court precedent. The brief came on the deadline day for parties to submit their positions on a petition filed in January by Jose Trevino and state Rep. Alex Ybarra (R-Quincy).
The case involves legislative maps drawn to strengthen Latino voter representation in the Yakima Valley region. U.S. District Court Judge Robert Lasnik approved the redrawn maps in early 2024 after the original boundaries — adopted by a bipartisan redistricting commission in 2021 and ratified by the Washington Legislature in early 2022 — were challenged by Latino voters contesting the 15th Legislative District lines. The revised maps affected more than 300,000 residents across 13 legislative districts in both eastern and western Washington.
The 9th U.S. Circuit Court of Appeals upheld Lasnik’s decision, but the legal landscape shifted in April when the Supreme Court issued its ruling in Louisiana v. Callais, a case that curtailed how race can be used in drawing legislative district boundaries.
The Core Dispute
Attorneys for Trevino and Ybarra have argued the redrawn maps constitute a racial gerrymander prohibited under the federal Voting Rights Act. Brown’s brief did not side with either camp on the underlying merits, but argued the lower courts deserve the first chance to apply the new Supreme Court precedent to the specific facts of Washington’s case.
“The lower courts should be given the first opportunity to apply that decision to the facts of this case,” Brown stated in the filing.
Washington Secretary of State Steve Hobbs took no position on the petition.
By the Numbers
- 300,000+ residents relocated into different districts under the redrawn maps
- 13 legislative districts altered by the revised boundaries
- 2021 — year the bipartisan redistricting commission first approved boundaries
- Early 2022 — when the Washington Legislature ratified those original boundaries
- 2031 — the next scheduled redistricting cycle in Washington state
Zoom Out
The Supreme Court’s April decision in Louisiana v. Callais marked a significant moment in redistricting law nationally, signaling greater skepticism from the high court toward explicitly race-conscious map-drawing. That ruling now sits at the center of multiple redistricting challenges winding through the courts, and Washington’s case may become an early test of how lower courts apply the new standard.
The broader question — how much weight state and federal authorities can give racial demographics when drawing district lines — has been contested across the Mountain West and Pacific Northwest, where shifting Latino populations have prompted both legal challenges and legislative responses in recent years. Cases like this one could influence how future maps are drawn well before the 2031 redistricting cycle arrives.
For context, the Supreme Court has also been active on questions involving federal election administration, including a Postal Service proposal tied to President Trump’s mail-in ballot executive order, underscoring the court’s growing role in shaping election-related disputes heading into future cycles.
What’s Next
The Supreme Court will now consider whether to take up the Washington redistricting petition. If the court accepts the case and remands it, lower courts would need to re-examine the Yakima Valley maps under the framework established in Louisiana v. Callais. Should the court decline, the 9th Circuit’s ruling upholding the current maps would stand — at least until the next scheduled redistricting round in 2031.
