EAC Issues Formal Investigation Report on DS200 Precinct Count Optical Scanner

from: EAC Staff on Dec 22, 2011

EAC has issued its Formal Investigation Report regarding the Election Systems & Software (ES&S) DS200 Precinct Count Optical Scanner in the EAC-certified Unity voting system. The conclusion is that three of the four anomalies that were originally identified are substantiated. The next steps are 1) a manufacturer site audit to evaluate testing and quality assurance practices and 2) issuance of a Notice of Noncompliance.

The three substantiated anomalies are:

  • Intermittent screen freezes, system lockups and shutdowns that prevents the voting system from operating in the manner in which it was designed.
  • Failure to log all normal and abnormal voting system events.
  • Skewing of the ballot resulting in a negative effect on system accuracy.

The manufacturer will have the opportunity to respond to the report and provide additional information if necessary. For more information about the process, please see the Voting System Testing and Certification Manual.

The investigation was initiated by EAC as a result of information contained in an article in The Cleveland Plain Dealer published on April 14, 2010, about a freeze/ shutdown issue experienced in Cuyahoga County, Ohio during pre-election testing. Section 7.4 of the EAC Voting System Testing and Certification Program Manual outlines the process for conducting a formal investigation. For more information, please see the Formal Investigation Report. Jurisdictions using EAC certified voting systems are identified on the website here.

The Process
The investigation process is initiated when EAC receives information that a voting system may not be in compliance with the applicable voting system standard or EAC certification program requirements. Upon receipt of such information, EAC initiates an Informal Inquiry to determine the credibility of the information. If the information is credible and suggests the system is non-compliant, a Formal Investigation is initiated. If the results of the Formal Investigation demonstrate non-compliance, the Manufacturer is provided a Notice of Non-Compliance. Before a final decision on decertification is made, the Manufacturer will have the opportunity to remedy any defects identified in the voting system and present any additional information for consideration by the EAC.
