Controversy in New Haven — The New Haven Unified School District was formed in 1965 by combining the Alvarado and Decoto School Districts and James Logan High School from the Washington Union School District. The joining of the school district was fairly harmonious. The only issue in the local newspaper, the “Union City Leader”, was the name of the district. The “Union City Leader” was advocating for the Union City Unified School District and was disappointed about the name “New Haven.” Two years after the founding of the school district, a huge controversy erupted in the district, leading to large public attendance at meetings, calls of illegal activities and a resolution by having a recall election. This paper documents the controversy in a chronological style.
