The ''Proceso'' shut down Congress, removed the judges on the Supreme Court, banned political parties and unions, and resorted to employing the forced disappearance of suspected guerrilla members including individuals suspected to be associated with the left-wing. By the end of 1976, the Montoneros had lost nearly 2,000 members and by 1977, the ERP was completely subdued. Nevertheless, the severely weakened Montoneros launched a counterattack in 1979, which was quickly put down, effectively ending the guerrilla threat and securing the junta's position in power.
