APA and other style guides rely mostly on The Bluebook: A Uniform System of Citation for Legal Citing.
For APA, consult the print Publication Manual of the American Psychological Association in Appendix 7.1: References to Legal Materials on pages 216-224 (in 6th edition). APA gives general examples but refers for more detailed information to the Bluebook. The major difference between the two, according to the APA Style Guide, is Bluebook lists references as footnotes but APA uses a reference list instead. Books and periodicals (other than law reviews) are cited in regular APA style.
For more detailed information on citing students should consult The Bluebook. State specific examples are available in the Bluebook; The Greenbook sets forth detailed Texas legal authorities.
