Why it matters

The players
Washington State Supreme Court
This is the highest judicial body in the state of Washington located in Olympia.
Barbara Madsen
She is a retired justice who participated in the majority decision regarding the initiative.
Washington State Republican Party
This political organization is currently urging voters to support five candidates for the state Supreme Court in the upcoming November election.
The details
The court's decision was supported by a majority that included retired Justice Barbara Madsen. This outcome follows a historical pattern in Washington where the judiciary has struck down voter initiatives on constitutional grounds, including Initiative 695 in 2000 and Initiative 976 in 2020.
Timeline
Initiative 695 was invalidated by the Court in 2000.
Initiative 976 was invalidated by the Court in 2020.
Initiative 2066 was approved by voters in 2024.
The Supreme Court released the decision on Initiative 2066 in September 2026.
Midterm elections occur in November 2026 with three initiatives on the ballot.
Political Context
The ruling follows a pattern established by the 2020 invalidation of Initiative 976 regarding state constitutional requirements. Opposition figures and political groups continue to contest the judiciary's authority in overturning outcomes decided at the ballot box.
The invalidation means that the provisions of Initiative 2066 will not be implemented as planned by voters. Citizens should monitor upcoming midterm elections in November 2026, as three other initiatives will appear on the ballot.
The takeaway
The court's decision highlights the importance of the single-subject rule in Washington's ballot initiative process. Voters should remain informed about constitutional requirements, as even popular initiatives can face legal challenges that prevent them from taking effect.
