Martínez de Hoz was himself indicted in 1988 for his involvement in the human rights abuses at Acindar and spent 77 days in jail. Quickly freed, he subsequently benefited from a pardon by President Carlos Menem in 1990. Returning to the world of high finance despite a 1992 conviction of operating a brokerage with a revoked licence, Martínez de Hoz became a member of the board of directors of two arbitrage houses, Rohm Group and the "Banco General de Negocios" ("General Business Bank").
