Military Rule of Evidence 504 recognizes two distinct spousal privileges: testimonial privilege preventing compelled spousal testimony and marital communications privilege protecting confidential marital communications. The testimonial privilege belongs to the testifying spouse, who may refuse to testify against their spouse in criminal proceedings. However, this privilege doesn’t apply in cases involving crimes against the spouse or children, or when spouses jointly participate in crimes.
The marital communications privilege protects confidential communications between spouses during marriage, surviving divorce for communications during marriage. Both spouses hold this privilege and may prevent disclosure. Communications must be intended as confidential – statements in third-party presence lack protection. Criminal planning between spouses doesn’t qualify as protected communication.
Military courts strictly construe exceptions, particularly for domestic violence or child abuse cases where spousal privilege would frustrate justice. The testifying spouse controls whether to claim testimonial privilege, preventing accused spouses from blocking voluntary testimony. Commands cannot pressure spouses to testify or waive privilege. Judges carefully instruct witnesses about privilege rights before testimony. Strategic considerations include whether claiming privilege creates negative inferences. The balance protects marital harmony while ensuring crimes against family members face prosecution. Recent trends limit spousal privilege scope in military justice, recognizing unique military community needs.
