Service members sometimes feel they were singled out, that others did the same thing without consequence while they alone face a court-martial. The legal name for that grievance is selective prosecution. The question is whether an accused can raise selective prosecution in a court-martial and what it actually requires. The answer is that selective prosecution can be raised, but it is best understood as a constitutional challenge to the prosecution itself, raised by motion to dismiss, rather than as an affirmative defense to the elements of the offense. And it is a difficult claim to win, demanding a demanding showing of both discriminatory effect and discriminatory purpose.
Selective prosecution is a challenge to the charging decision, not the conduct
It is important to be precise about the nature of the claim. An affirmative defense, in the usual sense, admits or addresses the conduct but provides a legal justification or excuse, such as self-defense or duress, that defeats criminal liability even if the act occurred. Selective prosecution is different. It does not say the accused did not commit the offense, and it does not justify the conduct. Instead, it argues that the decision to prosecute this particular person was made for an unconstitutional reason, so the prosecution should not proceed at all.
For that reason, selective prosecution is litigated as a motion to dismiss directed at the propriety of the charges rather than as a defense submitted to the panel on the merits. In a court-martial, motions raising defects in the preferral or referral of charges, and motions to dismiss on constitutional grounds, are presented to the military judge before findings. The military judge, not the members, decides the claim. This matters because it shapes how and when the issue must be raised and who bears the burden.
The constitutional standard
Selective prosecution doctrine comes from the constitutional guarantee of equal protection, which applies to the federal government, including the military, through the Due Process Clause of the Fifth Amendment. The governing standard is strict. A prosecutor’s broad discretion to decide whom to charge is presumed to be exercised in good faith, and a defendant challenging it must overcome that presumption with clear evidence.
To prevail, the accused must show two things. First, discriminatory effect: that others who were similarly situated and engaged in the same conduct were not prosecuted. Second, discriminatory purpose: that the decision to prosecute this accused was motivated by an impermissible consideration such as race, religion, or another arbitrary classification, or to retaliate for the exercise of a constitutional right such as protected speech. The constitutional rule is that prosecution may not be based on an unjustifiable standard such as race, religion, or other arbitrary classification, but mere selectivity in enforcement is not itself unconstitutional. Prosecutors necessarily make choices about whom to charge, and the fact that some offenders are charged while others are not does not, standing alone, establish a violation.
This two-part test reflects the Supreme Court’s framework for selective prosecution claims, which requires both that the policy had a discriminatory effect and that it was motivated by a discriminatory purpose. The Court has applied this same demanding standard even where a defendant claimed he was prosecuted for engaging in protected expression, recognizing that a person who is otherwise validly subject to prosecution is not insulated merely because the government was aware of his protected speech.
Why the claim is hard to win
The selective prosecution defense is rarely successful. The accused carries the burden, the presumption of regularity favors the government, and the required showing of discriminatory purpose is difficult to prove because it asks about the prosecutor’s actual motivation. Even obtaining discovery to develop the claim is demanding: a defendant generally must first make a credible threshold showing of both discriminatory effect and discriminatory purpose before a court will order the government to turn over its charging records. That threshold requirement prevents selective prosecution claims from becoming a routine fishing expedition into prosecutorial files.
In the military context, the difficulty is compounded by the deference courts extend to command and prosecutorial discretion within the disciplinary system. Showing that “similarly situated” service members went unpunished is itself complicated, because differences in rank, record, role in the offense, and the surrounding circumstances often mean that two cases are not truly comparable. Unequal outcomes can frequently be explained by legitimate distinctions rather than by impermissible discrimination.
A related but distinct military doctrine
Service members sometimes confuse selective prosecution with unlawful command influence, a uniquely military doctrine. Unlawful command influence concerns improper interference by command authorities in the justice process and follows its own framework, under which a defense showing of some evidence of such influence shifts the burden to the government to disprove its effect beyond a reasonable doubt. While both doctrines can challenge the legitimacy of a prosecution, they are separate. Selective prosecution is the equal-protection claim about discriminatory charging; unlawful command influence is about improper command interference. An accused who feels unfairly targeted should consider with counsel which doctrine, if either, fits the facts.
How to raise it properly
An accused who believes the prosecution is discriminatory should raise the issue through counsel by a timely pretrial motion to dismiss before the military judge. The motion should identify the impermissible basis alleged, present concrete evidence that similarly situated others were not charged, and offer whatever evidence exists of discriminatory motive. If the threshold showing is met, counsel can seek discovery of charging information to develop the claim further. Raising the issue early and on the record is essential, both because these defects are addressed before findings and because a clear record preserves the matter for appellate review.
Conclusion
An accused can raise selective prosecution in a court-martial, but it functions as a constitutional motion to dismiss the charges rather than as a traditional affirmative defense submitted to the panel. To succeed, the accused must overcome the presumption that the government charges in good faith and must prove both that similarly situated others were not prosecuted and that the decision to prosecute was driven by an impermissible purpose such as race, religion, or retaliation for protected conduct. The standard is exacting and the claim seldom prevails, but it remains a legitimate avenue where the facts support it. A service member who believes they have been unfairly singled out should consult experienced military defense counsel to assess whether selective prosecution, unlawful command influence, or another challenge offers a viable path.
