In Nelson v. Colorado the Supreme Court struck down a Colorado law requiring defendants whose criminal convictions have been invalidated to prove their innocence by clear and convincing evidence in order to receive a refund of fees, court costs, and restitution. According to the Court in a 7-1 opinion, this scheme violates the Fourteenth Amendment’s guarantee of due process.
Shannon Nelson was convicted on a number of charges from the alleged sexual and physical abuse of her children. Her conviction was reversed due to a trial court error; a new jury acquitted her of all charges. Louis Alanzo Madden was convicted of two sex crimes. The Colorado Supreme Court reversed his conviction; the state did not appeal or retry the case.
The only way Nelson or Madden could recover fees, court costs, and restitution was filing a civil claim under Colorado’s Exoneration Act, which requires them to show by clear and convincing evidence their actual innocence.
