According to the US Constitution, every citizen must be afforded due process of law. This means no one can be denied legal rights and all laws must have standard protections. This is more than being able to understand and confront an accuser if accused of a crime. Due process upholds educational service rights, or the quality or availability of public benefit entitlements.
People with disabilities are disproportionately entangled with the criminal justice system. The number of youth with disabilities in what has come to be called 'the school to prison pipeline' has grown with the advent of zero-tolerance policies. Access to accommodations is an imperative component of making sure justice is accessible to everyone. (Imagine someone who uses sign language being handcuffed during court.) Even when convicted, people with disabilities may experience abuse, discrimination, treatment refusal or other neglect in correctional or psychiatric facilities.
