retorsion

When the party, as a retorsion, disrated him and revoked his state as a campaigner, he left the party.

It is different from a reprisal in that the retorsion is always an action in conformity with international law, though unmistakably an unfriendly one.

In 1634 the Retorsion laws were made, whereby Catholic priests were expelled, their churches confiscated and handed over to Protestant preachers.

The typical methods of retorsion are the use of comparably severe measures against citizens of the foreign nation found within the borders of the retaliating nation.
