Firm annotation
Section 91 opens Chapter 2 (Search) with a cross-reference provision: it applies section 81/1 to searches mutatis mutandis rather than repeating its text. The drafting technique imports the safeguards of section 81/1 into the search context, so that the two provisions must be read together. Note that Supreme Court decisions bearing the citation section 91 frequently concern Penal Code section 91 (cumulative punishment for multiple offenses), a different provision, so care is needed not to confuse the two when researching case law under this section.
Why this matters in practice
In practice the significance of this section lies in Section 81/1, whose safeguards it imports into any search. If your person or belongings are searched, the lawfulness of that search is judged by the standards carried over through Section 91. When researching case law, do not rely on decisions citing Penal Code section 91, which addresses cumulative punishment, not searches. To assess whether a search of you was lawful, get a online consultation with a Thai lawyer.

Frequently asked questions
What does Section 91 of the Criminal Procedure Code do?
Section 91 opens the chapter on searches by providing that Section 81/1 applies to searches mutatis mutandis, so the two provisions are read together rather than Section 91 setting out its own separate rule.
Is Criminal Procedure Code Section 91 the same as Penal Code Section 91?
No. CrPC Section 91 concerns searches (by applying Section 81/1), while Penal Code Section 91 concerns cumulative punishment for multiple offenses; many case citations to section 91 refer to the Penal Code provision.
