Refusenik

[Renato]

[Refusenik] (Russian: отказник, otkaznik, from отказ, refusal) was an unofficial term for individuals, typically but not exclusively Soviet Jews, who were denied permission to [emigrate] abroad by the authorities of the former Soviet Union and other countries of the Eastern bloc.1 The term [refusenik] derived from the refusal, handed down to a prospective [emigrant] from the Soviet authorities.
Over time, refusenik has entered colloquial English usage for any type of protester.
