Why the us supremeCourt judtices are assigned or allotted to our citcuit courts of appeal?

U.S. Supreme Court justices do not directly assign themselves to circuit courts of appeal; rather, they oversee the judicial system as a whole. However, each justice is traditionally responsible for a specific circuit, which allows them to manage emergency matters and applications for stays or injunctions from that circuit. This distribution helps maintain a connection between the highest court and the appellate courts, ensuring efficient judicial administration and timely responses to pressing legal issues.
