This summary provides an overview of developments in school finance litigation since the United States Supreme Court's historic and lamentable 1973 ruling in "San Antonio Independent School District v. Rodriguez" that wealth-based discrimination in educational expenditures does not violate the equal protection clause of the Fourteenth Amendment to the federal Constitution. The failure of the Supreme Court to rule the Texas school finance system unconstitutional shifted school finance litigation to the state courts. The state cases are widely diverse in concept and scope depending on the state constitutional language, the mechanics of the school finance statute involved, and the factual setting. Some cases are broad-based attacks on the inequality of educational opportunity resulting from the systems concerned. Others focus on the state's failure to equalize for the effects of municipal overburden, urban education costs, or geographic concentrations of disadvantaged children. Fourteen pending cases in as many states and 22 terminated cases from 17 states, none decided prior to May 1974, are analyzed. (Author/PGD)
