Ballot Measure 71 amends the Oregon Constitution to direct the Legislative Assembly to meet every calendar year for a limited amount of time. Currently, the Oregon Constitution requires the legislature to meet every two years, in odd-numbered years only, and does not limit the length of the legislative sessions.

Provides that a session beginning in an odd-numbered year may not last longer than 160 calendar days. A session beginning in an even-numbered year may not last longer than 35 calendar days.

Allows a session to be extended for a period of five calendar days if approved by a vote of two-thirds of the members of each house of the legislature. A session may be extended more than once. An extension must begin on the first calendar day after the end of the immediately preceding session or extension period.

Allows the legislature to hold an organizational session for the purpose of administrative actions. The legislature may not take a final vote on any bill or other measure or reconsider a bill vetoed by the Governor at the organizational session.

Makes technical changes to sections of the Oregon Constitution necessary to maintain provisions tied to sessions held in odd-numbered years.

Does not change current constitutional provisions relating to special legislative sessions.
