Anyone who is in state custody pursuant to a state-court conviction has the right to file a petition for habeas corpus in federal court to review the constitutionality of their conviction or sentence. Traditionally, federal courts have ruled that someone who faces significant restraints on their freedom is “in custody” for purposes of being able to seek federal court review. However, in the case of Frank Corridore, a federal district court ruled that his sentence of lifetime electronic/GPS monitoring and sex offender registration do not satisfy the “in custody” requirement because the restraints on his freedom were not significant. In April 2022 the ACLU filed an appeal on behalf of Mr. Corridore in the Sixth Circuit, arguing that lifetime monitoring and registration sentences are significant enough restraints on liberty to qualify a case for federal review. Mr. Corridore has his every movement tracked by state officials, must report in person four times a year, cannot travel anywhere that lacks good GPS reception or electricity, and is subject to public humiliation because he has to wear an ankle monitor for the rest of his life. The appeal could affect the ability of hundreds of people in Michigan to challenge their underlying convictions when they remain burdened by sentences that require electronic monitoring and registration.
