May v. Ferndale Institution: Case lost because software was closed-source

A BLOG posting by Matthew Skala includes:

Some Federal inmates were transferred to a higher-security prison on the recommendation of a computerized risk-evaluation system. When they appealed, they wanted the details of the software's "scoring matrix"; and the Supreme Court allows the appeal, saying "Without the scoring matrix which provides information on the numerical values to be assigned to each factor and to the manner in which a final score is generated by the computerized tool, the inmates were deprived of information essential to understanding the computerized system which generated their scores and were prevented from formulating a meaningful response to the reclassification decisions."
