This data file consists of a detailed argumentation scheme and evaluation of the General and Actual Argument Model (GAAM) for the case of Robert Earl Hayes. This is the data that was used as the basis for the Chapter, "Argumentation Schemes, AI, & Criminal Justice: Evaluating Evidence in Miscarriages of Justice," in Data Governance for Justice & Human Rights: Forensics, Flow an Frontiers, for Bentham Science Books Current & Future Developments in Law Book Series. This data was gathered from court judgments and published news accounts of the investigations and trials of Robert Earl Hayes for the murder of two women. The data is separated into the six different scenarios put forward by defence and prosecution attorneys, and then organized into argumentation schemes. The arguments are then evaluated according to a method developed from Douglas Wilson and described in detail in the above chapter. The results of the argument evaluation assess the relative plausibility of the different scenarios, to determine the most plausible explanation for the evidence, as known in the case, at the time of evaluation.
