This new casebook is a problem-focused approach to the Religion Clauses and related materials on religion and government. It can also be adapted for teaching using the case method. This book contains not just the leading cases, but also: 1.) problems that provide good vehicles for discussing the law, 2.) a built-in outline of each doctrine, to be used together with the cases, and 3.) structured summaries of the main genres of policy arguments used in Religion Clause cases. It is also relatively concise at 450 pages of text, yet includes not just the purely constitutional material but also the important statutes—RFRA, RLUIPA, and Title VII's religious discrimination, accommodation, and harassment doctrines.
