1. Environmental Writs
The Writ of Kalikasan and Writ of Continuing Mandamus are extraordinary remedies under the Rules of Procedure for Environmental Cases (A.M. No. 09-6-8-SC). The Writ of Kalikasan applies when environmental damage is of such magnitude as to prejudice the life, health, or property of inhabitants in two or more cities or provinces, and may be directed against private or public entities. Conversely, the Writ of Continuing Mandamus directs a government agency or officer to perform an act unlawfully neglected in connection with the enforcement of environmental laws until full compliance with the judicial order is achieved.

2. Cybercrime Search Warrants
Under the Rule on Cybercrime Warrants (A.M. No. 17-11-03-SC), a Warrant to Search, Seize, and Examine Computer Data (WSSECD) is an order issued by a court authorizing law enforcement authorities to search a particular place, seize computer devices or data, and conduct an off-site or on-site forensic examination of the seized computer data. The WSSECD is utilized when law enforcement does not yet have physical custody of the target computer device or system and requires judicial authorization to gain access to the premises where the computer system or data resides.

3. Examination of Data
In contrast to a WSSECD, a Warrant to Examine Computer Data (WECD) is issued when law enforcement authorities have already lawfully obtained possession or custody of a computer device or system, such as through a valid warrantless search, plain view seizure, or lawful arrest. The WECD specifically authorizes officers to search and examine the computer data contained within the device already in custody. Obtaining a WECD ensures that forensic examination of previously seized electronic devices complies with constitutional protections against unreasonable searches and seizures.
