The orders were posted at a resort in Sakhu, Thalang, where the Supreme Court revoked land rights covering about 13 rai and ordered the occupants to vacate the property, demolish all structures and remove their belongings from the site.
Officials said the occupants have been given the legally prescribed period to comply. If they fail to do so, authorities will carry out the demolition and recover the costs from those responsible.
As is tradition, Mr Polapee was joined by a host of other officials taking the opportunity to visit Phuket, including senior officials from the Ministry of Interior, the Department of Land, the Department of National Parks, Wildlife and Plant Conservation (DNP).
Also present were Phuket Governor Chotinrin Kerdsum and other provincial officials during the inspection.
Speaking after the visit, Mr Polapee said authorities would continue investigating land documents suspected of having been issued unlawfully within conservation areas and would pursue legal action wherever evidence supported it.
"All agencies must work together carefully, transparently and strictly in accordance with the law," he said. "If irregularities are found, strict legal action will be taken without discrimination."
Officials said the case is one of six encroachment cases in Sirinat National Park currently under accelerated legal enforcement, with two already subject to final court rulings.
The second case involves about 12 rai of land in Cherng Talay, where the courts ruled that occupants must vacate the property after determining that forged Sor Kor 1 land documents had been used in obtaining title deeds.
According to the Department of National Parks, notices have now been posted requiring compliance with both court judgments. Failure to comply will allow authorities to enforce the demolition orders under the law.
Authorities have so far declined to officially identify the resort subject to today’s enforcement action. However, Thai media have reported that the case involves Fair & Firm Co Ltd, the owner of the Pullman Phuket Arcadia Naithon Beach resort.
According to those reports, the Supreme Court revoked a NorSor 3 Kor land-use document covering 13 rai of the resort after ruling that the land lies within Sirinat National Park. The resort occupies about 38 rai in total, with the Department of National Parks continuing to investigate the status of the remaining land.
Officials said the Department of Land has also been instructed to accelerate investigations into other land title documents suspected of having been unlawfully issued in conservation areas across Phuket.
