Fraud by Price Tag Substitution
The seller displayed multiple shirts at varying prices. While the seller was inattentive, Mr. Dee removed the price tag of a shirt priced at 100 baht and replaced it with a lower-priced tag taken from another shirt. He then presented the shirt to the seller and purchased it at the falsely indicated price of 10 baht.
Legal Analysis:
Mr. Dee intentionally misrepresented the true price of the goods by altering the price tag, thereby deceiving the seller into selling the shirt at a lower price. This constitutes a false representation of fact made with intent to induce another person to act to their detriment.
Conclusion:
Mr. Dee is liable for fraud under the Thai Penal Code, as his conduct involves deceit causing the seller to suffer loss.
