• The author and anyone they explicitly delegate may update the report;
• All administrators within the same clinic may cancel and reschedule appointments created by other administrators within that clinic;

A party that is neither an author nor a party who is extended authorship maintenance rights by policy, may only amend, reverse, override, replace, or follow up in other ways on this Act, whereby the Act remains intact and is linked to another Act authored by that other party.
