1. The Situation the Military Criminal Defense Attorney Faced
The client who sought a military criminal defense attorney requested a consultation with this firm with the desperate sentiment that “I cannot lose the 20 years of military career I have built up because of a single mistake.”
The Background of the Military Criminal Case
The client was caught in a drunk driving crackdown due to a momentary lapse in judgment, and the military disciplinary committee imposed on him the severe disciplinary measure of a reduction in rank (from master sergeant to sergeant first class).
At the time of the incident, the client’s blood alcohol concentration was approximately 0.09%, which corresponded to the level of license revocation under the Road Traffic Act.
On this basis, the military decided on a reduction in rank for violation of the duty to maintain dignity. However, the client’s conduct caused no personal or property harm, and the driving distance was extremely short, amounting to no more than a single, isolated mistake.
Despite the presence of sufficient mitigating circumstances, including 20 years of service with no disciplinary record, numerous commendations, a letter of reflection, and completion of traffic safety education, the disciplinary committee did not take these into account.
The military criminal defense attorney focused on this point, concentrating on proving that it was “excessive discipline.”
Issue Category | The Military Criminal Defense Attorney’s Assessment |
Appropriateness of the level of discipline | Given the blood alcohol concentration and the minor nature of the conduct, “demotion” violates the principle of proportionality |
Omission of mitigating circumstances | Commendation record, reflection, family circumstances, and a service record free of discipline were not considered |

2. Assistance Provided by the Military Criminal Defense Attorney
Rather than simply seeking leniency, the military criminal defense attorney took an approach with a logical structure that pointed out, on legal grounds, the limits of disciplinary discretion and the violation of the principle of proportionality.

Presenting the Legal Principles on the Nature of Discipline
The military attorney, citing Article 31(1) of the Ministry of National Defense Directive on the Handling of Disciplinary Matters for Military Personnel and Civilian Military Employees, emphasized that discipline is a sanction aimed not at ‘retribution’ but at ‘correction and rehabilitation.’
On this basis, the attorney argued that, given that the client had already been sentenced to a fine through the criminal process and had had his driver's license revoked, imposing a further demotion would violate the principle against double sanction and the principle of proportionality.
The attorney also cited the following precedent to set out the specific limits of disciplinary discretion.
Supreme Court Decision 83Nu130, June 23, 1983
Establishing the Sincerity of Reflection and the Will to Serve
In the statement of grounds for appeal, the military attorney attached a letter of reflection written by the client himself, a certificate of completion of traffic safety education, a confirmation letter from a superior officer, and petitions from fellow service members.
In particular, the petitions contained specific accounts of the client's habitually diligent service attitude, character, and standing within the unit, thereby emphasizing that the corrective purpose of discipline had already been achieved.
Systematic Analysis of Merit Records and Personnel Files
By organizing the personnel records of the client, who had served for 20 years without any disciplinary action, along with his Minister of National Defense commendation and his record of community contributions, the attorney supported the argument that “a single mistake should not bring down an entire military career.”
This material had a decisive influence on the decision to mitigate in the area of ‘service record and merit,’ a key mitigating factor in disciplinary sentencing.
Presenting Comparative Cases and Strengthening the Equity Argument
The military attorney presented precedents and disciplinary cases in which, among similar drunk driving cases, the punishment had been mitigated to ‘suspension from duty’ or ‘reduction of pay’ even where personal injury had occurred.
At the same time, the attorney logically established that, because this case involved no injury and a comparable blood alcohol level, demotion was an excessive disposition by social norms.
3. Outcome of the Assistance by the Attorney Specializing in Military Criminal Matters: Successful Mitigation
After closely reviewing the statement of grounds for appeal and the mitigating evidence submitted by the attorney specializing in military criminal matters, the disciplinary committee found the original disposition to be excessive, revoked the ‘demotion’ disposition, and mitigated it to ‘two months' suspension from duty.’
As a result of this decision, the client escaped the risk of discharge upon reaching the rank tenure limit and was able to return to his unit and continue his service as before.
With his eyes welling up, he said, “Now I want to restore my trustworthiness as a soldier,” and expressed his gratitude, saying, “Without professional assistance, I do not think I could have obtained this result.”

Drunk Driving and Discipline of Service Members
Where a service member drives while intoxicated in violation of Article 44 of the Road Traffic Act, military discipline may be imposed in addition to criminal punishment.
This is because such conduct is regarded as an act that seriously breaches military service discipline and the duty to maintain dignity.
The attorney specializing in military criminal matters, relying on Annex 1-4 (Disciplinary Standards for Drunk Driving) of the Enforcement Rules of the Military Personnel Disciplinary Decree, closely examined whether the level of discipline in this matter was reasonable.
Category | Blood Alcohol Level Standard | Level of Discipline |
First Drunk Driving Offense | Below 0.08% | Suspension from duty to reduction of pay |
0.08% or above, or refusal to be tested | Demotion to suspension from duty |
Ultimately, the attorney established that, in the case of a single violation with a blood alcohol level of 0.09% as in this case, there was sufficient possibility of mitigation under the disciplinary regulations.
Through this, the attorney specializing in military criminal matters obtained a mitigation decision that was legally justified, rather than a mere act of leniency.
