"This article examines the official response to the policy problems raised by the over two thousand Britons who went to fight for the Republic during the Spanish Civil War, with particular reference to the Foreign Enlistment Act (1870). Revived in January 1937 as a means of reducing the flow of volunteers and curbing the recruiting efforts of the Communist Party of Great Britain, the act proved embarrassingly unenforceable. Ambiguity over its applicability to the situation in Spain, combined with problems of evidence, meant that no charges were ever laid against volunteers caught attempting to leave for Spain or members of the recruiting organization of the CPGB. Though a complete failure as a legal tool, the Foreign Enlistment Act nevertheless symbolically underlined the British government's declared support for international non-intervention in Spain, and was never rescinded."
something wrong with this - laws dont go to sleep and need reanimation - they are always there used or not.
( a point such as this is not Too Difficult for the average AB reader is it?), ( Oh, OK yes it is, thanks)
and laws are not rescinded - repealed (= goes away ) or replaced ( with a better one )
The charges now are aiding terrorism
good treatment of this in the tv drama 'Next of Kin' a few weeks ago
and miney laundering for the internet warriors
thanks to the readers who have made it this far.
