On 20 March 2012, NMCCA decided United States v. Jones; and in doing so they have answered a question that was not unexpected, but took a little while to come.
In United States v. Miller, 63 M.J. 452 (C.A.A.F. 2006), CAAF decided prospectively that defense counsel must advise a client about the DoD sexual offender registration requirements when negotiating a PTA.
The question is how detailed must the advice be and what about additional state law requirements. There any number of offenses not listed in the current version of DODI 1325.7 where states now require registration.
