Interesting ACCA case pending

In United States v. Willis, No. ARMY 20071339, which is being argued on Thursday, the issue is:  “WHETHER THE PROSECUTION AGAINST APPELLANT WAS BARRED BY A GRANT OF DE FACTO IMMUNITY WHEN THE GOVERNMENT AGREED TO DISMISS CHARGES IF APPELLANT PASSED A POLYGRAPH EXAMINATION AND APPELLANT PASSED A POLYGRAPH EXAMINATION.”
