Which legal section does the Supreme Court state cannot be used to sue private probation companies?

The correct answer focuses on Section 1983, which refers to a part of the Civil Rights Act of 1871 that allows individuals to sue state actors for violations of their constitutional rights. The Supreme Court has determined that private probation companies do not qualify as state actors, meaning that they cannot be sued under this section for civil rights violations. This decision is rooted in the understanding that while private probation companies perform functions traditionally associated with public agencies, they are not government entities themselves. Therefore, they do not fall under the auspices of Section 1983, which is limited to actions taken by state actors.

Understanding this distinction is crucial, as it highlights the limitations of legal recourse available specifically against private entities operating in the realm of probation and parole. The other sections mentioned do not pertain to the specific legal context of civil rights lawsuits against private companies in the probation sphere, which is why they are not applicable in this scenario.
