The proposed legislation, known as the Second Amendment Preservation Act, aims to protect the rights of law-abiding citizens in Iowa to keep and bear arms. It establishes definitions for key terms such as "law-abiding citizen," "material aid," and "public officer," and outlines the responsibilities of state courts and law enforcement agencies to uphold these rights against federal infringements. The bill asserts that any federal actions that restrict the manufacture, ownership, or use of firearms within Iowa exceed the powers granted to the federal government and are therefore unauthoritative.

Furthermore, the bill imposes significant penalties on political subdivisions or law enforcement agencies that knowingly violate its provisions. Specifically, it establishes a civil penalty of $50,000 for each violation related to the enforcement of federal laws concerning firearms. It also allows citizens to seek injunctive relief in court against any such violations, with the possibility of recovering attorney fees and costs. The legislation emphasizes that providing material aid to federal officers in certain circumstances does not constitute a violation of the Act, thereby clarifying the boundaries of compliance.
