The Oregon Constitution is the foundational legal document that outlines the structure and function of the state government of Oregon. It was first adopted in 1857 and has undergone several amendments since then. The constitution establishes the three branches of government: the executive, legislative, and judicial branches, ensuring a system of checks and balances. In addition to outlining government structure, the Oregon Constitution includes provisions for individual rights and responsibilities. It addresses issues such as property rights, education, and taxation, reflecting the values and priorities of the state's residents. Amendments can be proposed by the legislature or through citizen initiatives, allowing for ongoing adaptation to changing needs.
