With the many access agreements ending this turn it is important to
remember that any forces within nations under now defunct access
agreements are still bound under those agreements and forces that passed
through nations under access agreements cannot be denied the right to
return to their homelands under the terms of those agreements.
10.3.1.2.1 General Access Rules: Once
inside another's province or controlled minor country, the voluntary
access permission to be there may not be rescinded (unless war between
the major power's negates the agreements).
10.3.1.2.1.1: Other corps or forces may
be denied entry, but those already there must be allowed to move, detach
garrisons and place depots as desired within any conditions already
set.
10.3.1.2.1.2: Forces may not be granted
voluntary access to move through a major power's territory and then
denied permission to return by the same route and under the same
conditions.
This may require some book keeping in the archives to keep track of any
units eligible to invoke the last clause.
