In the latest update regarding Sherley et al. v. Sebelius et al., the lawsuit challenging federal taxpayer funding of human embryonic stem cell research, a Motion was filed on May 18, 2011, to allow both sides to file supplemental briefs with the U.S. District Court. This motion to provide additional information to the Court was agreed upon by both sides. A similar previous motion filed on May 9 was opposed by the Department of Justice. The motions follow the April 29 decision by the Appeals Court to vacate the preliminary injunction issued by U.S. District Judge Lamberth in August 2010. While the Appeals Court ruling maintained the status quo regarding the flow of federal taxpayer funds for embryonic stem cell research, there are still a number of issues to be resolved, awaiting the decision of Judge Lamberth.

If the new motion is approved, both sides would be allowed to provide supplemental information in briefs due on or before June 24, 2011, and limited to 10 pages.
