What is the Maricopa County Employee Merit System Commission created by?

The Maricopa County Employee Merit System Commission was established by a resolution, which is a formal statement of a decision or expression of opinion put forth by an official body. Resolutions are often used by governing bodies to enact policies, create commissions, or express positions on various issues. This is particularly relevant in the context of government functions where formalizing processes is crucial.

In comparison, a contract would involve an agreement between parties, typically outlining the terms and conditions of a service or arrangement, which is not the case for the creation of a commission. An ordinance implies a law or regulation that has been enacted by a local authority, which could relate to broader legislative frameworks but isn't the mechanism used in this case. A policy refers to a guiding principle designed to influence decisions and actions but does not carry the formal enacting power that a resolution does. Thus, the correct choice highlights the official and formal process used to create the Maricopa County Employee Merit System Commission.
