Final answer:
The list of trial-related delegations is maintained by court systems, with resources like LibreTexts™ providing information on Supreme Court and appeals courts cases.
Step-by-step explanation:
The list of delegations pertaining to significant trial-related tasks is often maintained by the court systems or administrative offices within those systems. Specifically, the upkeep of such lists can be attributed to clerks of the court or administrative judges who manage the division of duties among court staff and legal officers. In higher courts, such as the Supreme Court or other appeals courts, resources like LibreTexts provide updated information that includes details on past and upcoming cases. These resources are valuable for legal professionals, students, and the public to stay informed on judicial proceedings.
