Short answer. Something different entirely. The court issues a commission or letters rogatory instead, but only when necessary or convenient, upon application and notice, and on terms that are just and appropriate; letters rogatory specifically are addressed to the appropriate judicial authority in that foreign country.

What the law says

A commission or letters rogatory shall be issued only when necessary or convenient, on application and notice, and on such terms and with such direction as are just and appropriate. Officers may be designated in notices or commissions either by name or descriptive title and letters rogatory may be addressed to the appropriate judicial authority in the foreign country.

A different mechanism for foreign depositions

For depositions that need to be taken in a foreign country, this section provides a mechanism genuinely distinct from an ordinary domestic subpoena: specifically, a commission or letters rogatory. Rather than the Philippine court simply directing a witness located abroad the same way it would direct a domestic witness, this specific alternative process is used instead for cross-border situations, recognizing that a Philippine court's ordinary compulsory process generally has no direct reach over someone residing outside the country.

When this mechanism is used

The issuance of a commission or letters rogatory here is not treated as automatic or routine in every case — it shall be issued only when it is genuinely necessary or convenient under the circumstances. It also requires both application and notice beforehand, and the terms and directions ultimately attached to it must be just and appropriate given the situation, rather than simply following one single fixed template regardless of context. The party requesting the commission or letters rogatory bears the burden of showing the necessity or convenience the rule demands; a request made simply for the litigant's own convenience, without any real obstacle to obtaining the deposition through ordinary means, does not automatically satisfy this threshold.

Designating the officer who will take the deposition

Officers may be designated within the relevant notices or commissions either by their specific name or by a more general descriptive title. This built-in flexibility allows the party seeking the deposition to either identify one specific person by name, or simply describe the general kind of officer, such as a particular consular or judicial official, who is to actually conduct the deposition once it happens abroad.

What letters rogatory involve

Letters rogatory, as clearly distinguished from a commission here, may instead be addressed to the appropriate judicial authority in the foreign country itself. This approach routes the underlying request through that other country's own judicial system, relying on that foreign authority to help facilitate the taking of the deposition rather than relying on a person directly designated beforehand by the Philippine court itself.
