Voting rights; prohibiting voter suppression and dilution. Effective date.

SB 1583 creates the Oklahoma Voting Rights Act to prohibit voting discrimination against protected classes, including racial, language minority groups, and Tribal communities. It bans election practices like at-large voting systems that dilute minority voting power and requires local governments to avoid policies creating unequal voting barriers. The bill mandates courts to interpret election rules in favor of voting access and defines "protected class" to include Tribal members. It directly affects all Oklahoma counties, cities, towns, and school districts governing election methods.
