Voting Rights Act of 1965 [SEP] Amendments
Congress enacted major amendments to the act in 1970, 1975, 1982, 1992, and 2006. Each amendment coincided with an impending expiration of some or all of the act's special provisions. Originally set to expire by 1970, Congress repeatedly reauthorized the special provisions in recognition of continuing voting discrimination. Congress extended the coverage formula and special provisions tied to it, such as the Section 5 preclearance requirement, for five years in 1970, seven years in 1975, and 25 years in both 1982 and 2006. In 1970 and 1975, Congress also expanded the reach of the coverage formula by supplementing it with new 1968 and 1972 trigger dates.
