Requisitioner is not to be confused with the agency confiscating, expropriating or 'requisitioning' land and building.

Docs., purchase orders or copies can also be 'requested' on a requisition form or card that I recall from export practice.

Extraordinary etc. Company Meetings can be 'called' or requisitioned by a shareholder who is termed a 'requisitionist' - a comparatively little-known term of corporate art and often, inaccurately, turned on ProZ into a 'caller' of such gatherings: such party would rather, in the UK etc., be the Board of Directors or Company Secretary..
