The constitution of Idaho is roughly modeled on the national constitution, with several additions. The constitution defines the form and functions of the state government, and may be amended through plebiscite. The state constitution presently requires the state government to maintain a balanced budget.

Idaho Code and Statutes
All of Idaho’s state laws are contained in the Idaho Code and Statutes. The code is amended through the legislature with the approval of the governor. Idaho still operates under its original (1889) state constitution.

Idaho has one of the strictest abortion laws in the nation. In April 2023, Idaho became the first state to restrict interstate travel for abortion services. Nearly all abortions are banned and private citizens can sue abortion providers. The Idaho Supreme Court has ruled there is no constitutional right to abortion. A federal judge ruled in 2022 that doctors cannot be punished for performing an abortion to protect a patient’s health. The state abortion laws have led to an outmigration of physicians who specialize in maternal/fetal care.
