Legal Review Case: AI Healthcare Service Terms of Use & Privacy Policy
Decent Law Firm’s Corporate Legal Team conducted a comprehensive legal review of the Terms of Use and Privacy Policy for an AI-based infant head shape analysis and customized chatbot consultation service. The service operates as a web-based platform where users upload vertex (top-of-head) photographs, which are analyzed by AI to quantify cranial proportions—left/right, front/back, and diagonal ratios—and subsequently provide informational guidance through an AI chatbot. The primary legal issues addressed in this engagement were ensuring the lawful processing of biometric data classified as sensitive personal information, and mitigating regulatory risk by clearly defining the service as non-medical in nature.

Full Dismissal of All ClaimsCivil
Successful Defense in a Damages Claim Lawsuit | KRW 630 Million Claim Fully Dismissed
The defendant had been in a de facto marital relationship with the deceased since approximately 2005. The deceased was later arrested and indicted for fraud after conspiring with a third party to defraud the plaintiff company of approximately KRW 3.6 billion. On the day of the offense, KRW 630 million was transferred to the defendant’s bank account. Relying on the facts that the defendant was in a de facto marital relationship with the deceased and that a large sum was transferred shortly after the crime and used for loan repayments and cash withdrawals, the plaintiff filed a civil damages lawsuit. The plaintiff alleged that the defendant either participated in the fraud or assisted in concealing criminal proceeds. In an unjust situation where the legitimate exercise of her rights was misconstrued as concealment of criminal proceeds, the defendant sought assistance from Decent Law Firm’s Civil Litigation Team to mount a legal defense and establish the substantive truth.

Suspended Sentence GrantedCriminal
Suspended Sentence Secured in a Combined Drug and Prostitution Criminal Case
The client, Mr. A, was an office worker employed at a private company. While maintaining an ordinary daily life, he was exposed to an unofficial distribution channel through Telegram, which led to the use of controlled substances. During the investigation, authorities confirmed that Mr. A had used methamphetamine and had purchased, possessed, and consumed ketamine. It was further revealed that, at certain points, he engaged in acts of prostitution while under the influence of these substances. As a result, the case expanded beyond a simple drug offense and developed into a high-risk criminal matter involving both violations of the Narcotics Control Act and prostitution-related offenses. At the time of first contact from the investigative authorities, Mr. A did not fully grasp the seriousness of the situation. He faced extreme psychological pressure, realizing that a single misjudgment could destabilize his entire life. Given the gravity and complexity of the combined charges, immediate and strategic legal intervention was essential.

Legal Review Opinion on the Compliance of a Crypto Asset Exchange Service (Kimchi Premium Arbitrage)
The client operates a business overseas and had been utilizing a cryptocurrency arbitrage strategy commonly known as the “Kimchi Premium” in order to reduce remittance costs when transferring funds to Korea. During this process, the client began assisting acquaintances with currency exchange transactions in return for a small commission. As the frequency and volume of these transactions gradually increased, the client became concerned about potential violations of the Foreign Exchange Transactions Act and the Act on Reporting and Use of Specified Financial Transaction Information (AML Act). Recognizing that the matter required more than general criminal law advice, the client sought professional legal counsel from Decent Law Firm’s Digital Asset Team, which possesses in-depth knowledge of cryptocurrency technology and regulatory enforcement practices.

Medical Device Act Compliance Review for AI Healthcare App
The Corporate Practice Group at Decent Law Firm conducted a comprehensive legality review for the new service of Healthcare Startup A, which utilizes AI vision technology to analyze body proportions and provide health management information. The service in question is an app that analyzes user-uploaded photos to inform users about body ratios and symmetry. Such services tread a fine line between general "Healthcare" and regulated "Medical Practice," creating a significant risk of being misclassified as an unapproved medical device under Korean law. Consequently, the client retained our firm—specifically our attorneys specializing in the Medical Device Act—to ensure a legally secure business structure prior to the service launch.

Detention Warrant RejectedCriminal
Enticement of a Minor Case – On-Site Arrest but Detention Warrant Rejected at Prosecutorial Stage
The client, an active police officer, used a location-based chat application late at night out of curiosity. He communicated with individuals who identified themselves as 20-year-old women. After arranging a meeting, he engaged in sexual activity inside his vehicle and was immediately arrested in flagrante delicto by undercover officers. The investigation later revealed that the individuals were, in fact, minors. The client was consequently investigated for the offense of Purchasing Sexual Acts from a Minor under the Act on the Protection of Children and Juveniles. Considering the seriousness of the allegation and the client’s occupation as a police officer, the authorities were actively considering seeking a detention warrant. A conviction would not only result in criminal penalties but also trigger automatic dismissal under the National Public Officials Act. To assert his innocence and protect his career, the client sought the assistance of Decent Law Firm’s sex-crime defense team.

This case involved multiple charges under the Narcotics Control Act, including the use and trafficking of methamphetamine, smoking and selling cannabis seeds, and possession and use of ketamine.

The defense filed a counter-appeal citing unfair sentencing practices.
