Caption

IMMIGRATION COOPERATION AND ENFORCEMENT ACT – Amends existing law to revise provisions regarding illegal entry, to remove provisions regarding illegal entry, and to provide for certain affirmative defenses.

Summary

S1260, titled the Immigration Cooperation and Enforcement Act, revises Idaho’s illegal entry laws by clarifying how certain provisions are defined and applied. The bill’s statement of purpose says it clarifies the relationship to federal immigration law and specifies that the statute applies to individuals 18 years of age and older. The caption also indicates that the measure revises existing illegal entry provisions, removes some provisions, and adds certain affirmative defenses. In practical terms, the bill updates the state’s immigration-related criminal statutes and narrows or refines how they operate. It is framed as a clarification measure rather than a new enforcement mandate, and the fiscal note states it should not affect the state budget or impose additional duties on state or local law enforcement. The bill was ultimately enacted and signed into law, with an effective date of July 1, 2026.

Impact

The bill amends Idaho law governing illegal entry and related immigration enforcement, including statutory definitions, the scope of the offense, and available affirmative defenses. It also expressly ties the state provisions more closely to federal immigration law and limits application to adults 18 and older. Because the bill removes some existing provisions while revising others, it changes the structure of the state’s immigration code without, according to the fiscal note, creating new budgetary or operational obligations for law enforcement or other state agencies.

Sentiment

The voting record suggests the bill had majority support in both chambers, passing the Senate 29-6 and the House 57-8. That pattern indicates generally favorable sentiment toward the measure among lawmakers, with enough bipartisan or cross-party support to clear both chambers comfortably. The available materials do not include committee testimony, so the public discussion reflected here is limited, but the bill’s framing as a clarification and enforcement measure appears to have helped it advance.

Contention

The main points of contention likely centered on immigration enforcement, the scope of state authority, and the decision to revise or remove existing illegal entry provisions. The addition of affirmative defenses may have been important to supporters seeking to avoid overbroad application, while opponents may have objected to expanding or formalizing state involvement in immigration-related enforcement. The bill’s limitation to persons 18 and older and its reliance on federal immigration law suggest lawmakers were also focused on avoiding ambiguity and potential legal conflict.
