C. What bodies are covered by the law?

The Arizona OML applies to “any public body.”  A.R.S. § 38-431.01(A).

“Public body” is defined as

the legislature, all boards and commissions of this state or political subdivisions, all multimember governing bodies of departments, agencies, institutions and instrumentalities of the state or political subdivisions, including without limitation all corporations and other instrumentalities whose boards of directors are appointed or elected by the state or political subdivision. Public body includes all quasi-judicial bodies and all standing, special or advisory committees or subcommittees of, or appointed by, the public body.

A.R.S. § 38-431(6).  What constitutes a “public body” is fairly expansive and may turn on unique facts or circumstances.  For example, what constitutes “institutions and instrumentalities of the state or political subdivision” might depend heavily on the relationship between the body and the political subdivision.
