Procurement Director Edward Armstrong must have a feeling of deja vu.Disclosure provisions in the state’s competitive bidding process have landed him in the hot seat again, this time as a defendant in a lawsuit filed last week by DSM USA Insurance Co. Inc. of Boston, better known as DentaQuest.The complaint, filed by the McDaniel Richardson & Calhoun law firm in Pulaski County Circuit Court, also names the Office of State Procurement and the Department of Finance & Administration as defendants. It claims Armstrong unfairly disqualified DentaQuest after it finished first among four companies in the bidding for two companies to provide dental HMO services for the Arkansas Medicaid program.The OSP named DentaQuest and Delta Dental of Arkansas as the anticipated contract winners in December, but that wasn’t the last word.
