The Le Chapelier Law was an important law in Belgium, as it implicitly disallowed the proletariat from associating, or organising a strike.
As the parliament at the time (1864) was dominated by the Liberal Party and Catholics as the only two parties, with a slight majority of the Liberal Party, I am puzzled why the law was annulled. Both groups had interests in keeping the working class quiet.
I can imagine the Liberal Party annulled the law because it was against the economic principles (although it protects the free market), but I find this hard to believe. Only wealthy people were allowed to vote so the parliament was dominated by people with interests in keeping the working class quiet.
Why was the law revoked?
