Oregon Law

C. Meetings and Deliberations Subject to the Law

1. Public Meetings

All meetings of a governing body must be open to the public, unless Public Meetings Law permits the body to meet in executive session or otherwise provides an exception.[591] A “meeting” is the convening of any governing body “for which a quorum is required in order to make a decision or to deliberate toward a decision on any matter.”[592]

In addition, a quorum of a governing body may not meet in private for the purpose of deciding on or deliberating toward a decision on any matter, unless an exception applies.[593]
