Statutory text (Thai original)
ในกรณีที่ไม่มีข้อกำหนดของประธานศาลฎีกาตามมาตรา ๒๕๐ กำหนดไว้เป็นอย่างอื่น ให้นำบทบัญญัติในลักษณะ ๑ ว่าด้วยอุทธรณ์มาใช้บังคับโดยอนุโลม
English translation
In a case where there is no regulation of the President of the Supreme Court under Section 250 providing otherwise, the provisions in Title 1, on Appeal, shall apply mutatis mutandis.

Firm annotation
Section 252 is the bridge that carries the appeal Title's rules up to the dika stage, so the Code does not have to restate them for the Supreme Court. It applies mutatis mutandis and only where the President's regulations under Section 250 do not provide otherwise. In practice courts cite it constantly, pairing it with sections such as Section 142(5) through Section 246 to raise public-order points on their own motion, with Section 225 to bar issues not properly raised below, and with Sections 242 to 245 for the disposition and reach of a dika judgment. It is the current successor to the earlier mutatis mutandis provision for dika under the pre-2015 numbering. The statutory text provided here is truncated after the words that introduce the borrowed provisions.
Why this matters in practice
The everyday effect of Section 252 is that most rules you know from the appeal stage carry over to a dika, including the strict bar on raising a new issue that was not properly argued in the lower courts. If a point was not ventilated below, you usually cannot spring it in the Supreme Court, so build your record early. Because the interplay of sections is technical, take advice from a Thai lawyer when planning a dika.

Supreme Court Judgment No. 367/2568 (2025)
An issue raised for the first time in a dika, not properly argued in the lower courts, is barred under Section 225 paragraph one applied to the dika through Section 252, and the Supreme Court will not decide it.
The defendant argued in the dika that the disputed house belonged to another person, a fact raised for the first time on dika. The Supreme Court held it barred as an issue not properly raised in the lower courts, under Section 225 paragraph one with Section 252, and refused to decide it.

Supreme Court Judgment No. 4759/2568 (2025)
A point of law concerning public order may be raised by the Supreme Court on its own motion even where no party has dika'd, using Section 142(5) applied to the dika through Sections 246 and 252.
An order requiring the respondent to pay default interest on property forfeited to the State was unlawful. The Supreme Court held this a public-order point it could raise on its own motion and corrected it, applying Section 142(5) with Sections 246 and 252.

Frequently asked questions
Do the appeal rules apply to a dika?
Yes. Under Section 252, where the President's regulations under Section 250 do not provide otherwise, the appeal Title's rules apply to a dika mutatis mutandis.
Can I raise a new issue for the first time in a dika?
Generally no. Through Section 252 the appeal-stage bar in Section 225 applies, so an issue not properly raised in the lower courts cannot usually be argued in the Supreme Court.
