Supreme Court Rules Jeonjangyeon Subway Sticker Protest as Criminal Property Damage

On May 20, 2026, the Supreme Court of South Korea ruled that the sticker protest campaign conducted by Jeonjangyeon, a prominent disability rights group, constituted the criminal offense of property damage. The activists had affixed large, difficult-to-remove stickers criticizing the government’s disability policies onto walls, elevators, and platform screen doors across multiple subway stations. The protests, which occurred during morning rush hours over several months in 2025, led to significant cleaning and repair costs for the transit authority. While the defendants argued their actions were a legitimate form of symbolic speech protected by the constitution, the Court held that the unauthorized physical alteration of public property, requiring substantial effort and expense to restore, clearly exceeded the boundaries of protected expression and satisfied the elements of willful destruction of property under the Criminal Act. The ruling upheld a lower court’s decision and imposed criminal fines.

The Supreme Court affirmed the lower courts' guilty verdicts, finding that the sticker campaign met the legal criteria for property damage under Article 366 of the Korean Criminal Act. The activists were sentenced to fines, with the court emphasizing that the necessity of repairing and cleaning the defaced public facilities involved considerable expense and manpower, thus constituting tangible harm to property utility. The ruling rejected the appeal that the act was protected symbolic speech, establishing a binding precedent.

The central dispute was whether affixing large, adhesive stickers onto subway facilities as a method of protest constitutes criminal property damage, or whether such conduct should be considered constitutionally protected symbolic political expression. The defense argued the stickers were a necessary act of civil disobedience to highlight the government's failure to uphold disability rights, and that their removal did not cause permanent structural damage. The prosecution contended that the substantial restoration costs and the unauthorized, obstructive nature of the act clearly fell within the legal definition of destroying or damaging another's property.

The decision sent shockwaves through South Korea's civil society, particularly among disability rights and progressive activist communities. It was widely condemned by advocacy groups as a severe judicial restriction on the right to protest, effectively criminalizing a visible, non-violent form of direct action for marginalized groups. Meanwhile, conservative commentators and public transit authorities welcomed the ruling, asserting it reaffirmed the need to protect public property and maintain order against disruptive demonstration methods. The case intensified the ongoing national debate on the limits of civil disobedience and the balance between freedom of expression and property rights.
