See an introduction to LUBA and how it handles land use appeals. It answers the questions most often asked by persons who wish to represent themselves in appeals. This is not a procedure manual, nor is it a legal document.
The laws governing LUBA are in Oregon Revised Statutes (ORS) Chapter 197 and in procedural rules adopted by LUBA. Read the statutes and rules before becoming involved in an appeal. The statutes are available online and at most public libraries.
