"When an employee brings a lawsuit to enforce workplace rights, can an employer-defendant ask questions about the employee's immigration status? Workers may be intimidated by the prospect of free-wheeling discovery into their immigration status, and some workers may even forgo litigation entirely, just to avoid the discovery process. In recent years, many federal courts have heard discovery disputes over immigration status. From the leading 9th Circuit case (Rivera v. NIBCO, 364 F.3d 1057 (9th Cir. 2004)), through more recent decisions, this article reviews the issues that courts weigh when ruling on these discovery disputes in employment litigation. The article also proposes a framework for some bright-line rules to govern these discovery issues in future cases." - Thomas A. Doyle, Wexler Wallace, LLP, 28 ABA Journal of Labor & Employment Law 405, Spring 2013.
