Note: This is a PDF file and requires an Acrobat-compatible reader.
This also covers the Doyle/Darling arguments and the rebuttal. It serves as a preview for the oral arguments presented today.
I can't find the Doyle brief published. However, the other anti force giving oral argument was Robert Muise, trial counsel of the Thomas More Law Center, Ann Arbor, Michigan. There are press releases on the general content here and here.
