Concerning firearms background check.
HB 2521 establishes a centralized, automated firearms background check system in Washington State, requiring all firearm dealers to use this system for background checks before sales or transfers. The system must check against multiple databases (including state crime records, court systems, and health databases) and provide dealers with instant results via a web portal or phone, including unique identifiers for each check. It sets a $18 maximum fee for background checks (replacing the existing fee) and creates an appeal process for applicants denied due to errors. The bill directly affects firearm dealers (who must use the system) and firearm purchasers (whose backgrounds are checked), with the system mandated to be fully operational by July 1, 2025.

MINOR
The document was converted from a draft bill text into a formal certification of enrollment, confirming that House Bill 2521 has been passed by both the House and Senate. This change adds official signatures, vote counts, and filing dates, which are necessary to make the bill a law but do not alter the bill's actual policy content.
TECHNICAL
Added certification header, vote tallies, and signatures from the Speaker of the House and President of the Senate to formally record the bill's passage.
Inserted a certificate statement from the Chief Clerk attesting that the attached text is the final version passed by the legislature.
Removed the draft bill number 'Z-0581.1' and replaced it with the final 'Passed Legislature' status and filing information.
