1. Client Situation and Facts

The client, a Chinese national, was residing in Korea as a university student while operating a side business of purchasing Korean cosmetics online and reselling them in China. To convert the earned yuan into won for use in Korea, he used an online exchange service, receiving part of the amount the next day in Korean won.

RESPONSE

Obtaining Exonerating Evidence

Ma-Jung submitted a request for document submission to secure investigation records from the police, which confirmed that the client had no involvement or aiding in the voice phishing crime. These records were pivotal in demonstrating that the client was merely an account holder and another victim of a larger scam, without any financial gain from the crime.

Demonstrating Legitimate Transactions

Ma-Jung proved that the amount the client attempted to exchange was consistent with his earnings from his legitimate business activities. The immediate conversion of funds the following day further supported the argument that the client was unaware of the fraudulent nature of the deposited money.

Disproving Elements of Fraud

To substantiate the client's innocence, Ma-Jung emphasized that the client neither engaged in deceitful behavior nor gained any illicit financial benefit, key components of fraud. The legal team worked diligently to highlight the client's legitimate business operations and lack of criminal intent.

3. Case Outcome and Client Benefit

The court dismissed the plaintiff's claim for unjust enrichment, ruling that the client did not knowingly benefit from the proceeds of the voice phishing scam. This outcome relieved the client from the financial burden and legal uncertainties , allowing him to continue his studies and future career plans in Korea without further legal obstacles.
