Finding the history of a judicial opinion or a statute is relatively straightforward, if only because we do that research so often. This is not the situation when researching the history of a regulation or other administrative rule, especially at the state level.
Also, most of the time we’re looking to update the law (regulation, case, or statute), that is finding out how the particular law reads today, not what it said 10 years ago or how it got to be what it is now, that is, what happened x years ago that made the rule change to what it is now.
So, how do you find the history of an Oregon administrative rule?
