We don't generally cover statute of limitations-type issues (except for class action tolling) because they tend to be too state-specific and fact-bound to be of much general use. We're making an exception for today's decision in Gazal v. Boehringer Ingelheim Pharmaceuticals, No. 10-3129, slip op. (8th Cir. July 28, 2011), because it decides a statute question we've seen raised in any number of jurisdictions. That's whether a plaintiff, knowing full well what he thinks is happening, is allowed to delay suit under until the scientific proof of causation would satisfy the relevant Daubert standard of the jurisdiction.
