Cunningham Lindsey Claims Management, Inc. v. Oklahoma State Ins. Fund, 38 P.3d 248, 2002 OK CIV APP 7

A state agency did not have authority to modify a contract approved by the State Purchasing Director even though agency-specific statutes authorized the agency’s Commissioner, in conducting the business of the agency, to enter into certain contracts.  The court stated that the agency-specific statutes were merely legislative intent to designate the Commissioner as the party who would negotiate on behalf of the state agency.
