The results of new and/or continued litigation challenging the constitutionality of state school financial systems since the publication of the first volume of this study, which examined the history of such litigation from 1912-1971, are presented in this second volume. Recent cases illustrate two trends: the increase in the number and expediency of judicial cases; and the use of adequacy and efficiency as new major lines of reasoning. Analysis of cases is applied to the Illinois system of state aid, and common characteristics are identified and used to predict the likely outcome of a similar challenge to the Illinois judicial system. Appendices include information on upheld and overturned state school finance systems and a note on "Abbott v. Burke." (41 references) (LMI)
