Code of Civil Procedure Article 287

In the case of any obstacle that makes it impossible to designate the time in advance for taking evidence, the court may, on motion, designate a period of time within which the evidence shall be taken. Notwithstanding, the evidence shall still be taken after such period expires insofar as the litigation will not be delayed as a result.
中文原文 民事訴訟法第287條
因有窒礙不能預定調查證據之時期者,法院得依聲請定其期間。
但期間已滿而不致延滯訴訟者,仍應為調查。
