N/A (Colonial Legislation)	1878	The Arms Act, 1878, regulated the possession, manufacture, and sale of firearms and ammunition. It was frequently used to prosecute HRA members found with weapons or bomb-making materials, criminalizing their efforts to arm for revolution.	Severely restricted access to arms for revolutionaries, leading to clandestine manufacturing and procurement, and providing a legal basis for arrests.
N/A (Colonial Legislation)	1908	The Explosive Substances Act, 1908, was enacted to counter the growing use of bombs by revolutionaries. It made the possession, manufacture, or import of explosive substances with unlawful intent a serious offense.	Directly targeted HRA's bomb-making activities, leading to arrests in cases like the Dakshineswar Bomb Case and providing grounds for severe sentences.
N/A (Colonial Legislation)	1913	The Criminal Conspiracy Act, 1913, broadened the definition of conspiracy, making it easier to prosecute groups planning illegal acts, even if the acts were not fully executed. This was a powerful tool against organized revolutionary groups.	Crucial in prosecuting the Kakori Conspiracy Case, allowing the British to implicate multiple members in a planned act, regardless of individual roles.
N/A (Colonial Legislation)	1860 (Section 124A added 1870)	Section 124A of the Indian Penal Code (Sedition Law) criminalized any act or speech that brought or attempted to bring into 'hatred or contempt' or excited 'disaffection' towards the government. It was a primary legal weapon against nationalist propaganda.	Used to suppress HRA's manifesto 'The Revolutionary' and other publications, leading to charges against ideologues like Sachindranath Sanyal for inciting rebellion.
