In June 1794, which law was instituted that altered the legal proceedings during the revolution?

The Law of 22 Prairial, instituted in June 1794, significantly altered the legal proceedings during the French Revolution by streamlining the judicial process and intensifying the existing revolutionary justice system. This law removed certain legal protections for individuals accused of political crimes. It allowed for the trial of a defendant without the need for a formal defense, effectively leading to expedited trials and increased executions. The law facilitated a greater number of convictions based on perceived political alignment rather than evidence, marking an escalation in the Reign of Terror. This restructuring corresponded with the government's efforts to eliminate dissent and further consolidate power during a time when the revolution was facing both internal and external threats.

Other options, while relevant to the broader context of the revolution, do not specifically relate to the alterations made in legal proceedings in June 1794. The Law of Frimaire dealt primarily with administrative reorganizations, the Law of Suspects established broad criteria for arresting individuals deemed enemies of the revolution, and the Levee en masse referred to the mass conscription of soldiers rather than judicial processes. These laws contributed to the revolutionary environment, but it was the Law of 22 Prairial that directly refined and intensified judicial proceedings at that critical juncture.
