It appears that settlement with federal officials is unlikely. Ursack's case is scheduled to be argued in a motion for summary judgment on July 31, 2009. It is impossible to predict when the court will render a decision or what that decision will be.

There has been some movement in Ursack's lawsuit against federal officials. The parties and their lawyers met in San Francisco on February 27, 2009. Some progress was made, but at this time there is no determination if Ursack will be approved for use in Yosemite National Park, Sequoia and King's Canyon National Parks, or Inyo National Forest in 2009. All parties are continuing to work toward a prompt resolution. Updates will be posted here as appropriate."
