Section 44 of the interim charter could be used to expedite prosecution proceedings in the Bonanza Resort forest encroachment case, according to the provincial police commander.
The Bonanza Resort made headlines after law enforcement officers, including the 2nd Army Region, inspected the resort's accommodation buildings and racetrack in Pak Chong district's tambon Khanong Phra last week.
More than 151 rai of the resort's land allegedly encroaches on Kho Sied-Ar, Pa Khao Nok Yoong and Pa Khao Ang-Hin national reserve forests.
Nakhon Ratchasima police chief Thakun Natthisi said police are checking land documents with forestry officials and the land owner, Bonanza Golf and Country Club Co.
The documents will be compared with land survey data obtained by global positioning system to determine which areas are encroached upon.
Pol Maj Gen Thakun said Section 44 of the interim constitution may be used to allow Prime Minister Prayut Chan-o-cha to speed up the Bonanza investigation.
How fast the probe proceeds also depends on the amount of time it will take the military and state agencies to examine evidence, he added.
He conceded the investigation process is unlikely to be wrapped up within 30 days.
Meanwhile, Sunthorn Kanhachan, the forest protection unit chief in Pak Chong district, led his team and police officers on Thursday to erect placards announcing the land seizure on the resort's racetrack.
The team was unable to enter the race circuit as its gates were closed.
Mr Sunthorn is in the process of acquiring access to the compound.
Pakchong investigator Banyat Thangklang said officials involved with issuing Nor Sor 3 Kor documents for the five land plots on which the racetrack is built will be summoned for questioning.
Interior Minister Anupong Paojinda said the ministry has asked the Department of Lands to examine the Nor Sor 3 Kor documents issued for the land and set up a panel to investigate it.
If the documents are found to have been issued illegally, the officials involved will be punished and the land ownership papers revoked, he said.
An Agricultural Land Reform Office (Alro) source said the agency is set to survey more than 100 rai of land in Nakhon Ratchasima's Khao Yai and Chiang Rai, allegedly occupied by a popular TV anchor and a well-known former director-general of a state department.
The probe comes after the Alro discovered ownership papers for the land were issued unlawfully.
An Alro legal team will survey the encroached land plots and retake them, the source said. No word was available on the fate of the structures built on the land.
