# Get mandate history

> Accepted cases (Aktenzeichen).

Main-case-centric: the list returns **main cases only**.
Sub-cases are reachable through the main case detail representation and
direct detail/subresource URLs, not a flat list expansion. Tenant-scoped by
the authenticated company.

Sub-resources of one mandate:

  * payments — the reported, non-ignored payments
  * documents — claim-document metadata and a proxy-stream download
  * history — published client activity, related resources, and attachments.
    A main case includes its subcases; a subcase includes only itself.

The sub-resource operations resolve the mandate **including sub-cases** —
unlike the list, which hides sub-cases — so an individually-addressable
sub-case's own track stays reachable. These public mandate operations are
reads.
