delivered the opinion of the court.
On August 8, 1919, Eafael Martorell petitioned the District Court of San Juan, Section 2, for a writ of mandamus against llamón Siaca, Jr., commanding him to issue a copy of each of the following documents; (a) A will made by Manuel Fernández Alonso on June 25, 1897; (b) a deed executed on July 27, 1900, before notary Alvarez Nava for the liquidation, partition and settlement of the estate of the deceased Fernández Alonso; (c) a deed executed on November 22, 1916, before notary Francisco Soto Gras for correcting the said partition.
The petitioner alleged that the respondent, a notary public, had in his custody the said documents; that he had brought an action for their annulment in the District Court of Arecibo and needed copies of them in order to prove the allegations of the complaint; that on the day before the *254court bad granted big motion for an order directed to tbe respondent for tbe issuance of tbe copies, be having previously verbally requested tbe respondent to issue them; that tbe respondent bad both refused tbe verbal request and also ignored tbe order of tbe court authorizing him to issue tbe copies, and that tbe respondent’s refusal to issue tbe copies prejudiced bis rights because of bis urgent necessity of offering them in evidence at tbe trial of tbe case.
' By an order of tbe same, date, August 8, tbe Court of San Juan granted the petition and fixed tbe time within which the respondent should appear and show cause why he bad not obeyed tbe order of tbe court. Tbe respondent appeared and filed a lengthy answer, alleging, among other things, that tbe petitioner bad not showed that be was an interested party in the documents and that the court’s first order only authorized him to issue the copies and did not command him to do so.
It does not appear that any evidence was examined and tbe district court finally, on August 11, 1919, granted the petition for a writ of mandamus only with regard to the deed of November 22, 1916, correcting tbe partition of tbe estate of Manuel Fernández Alonso, without costs. From that ruling tbe respondent took this appeal.
In tbe opinion on which tbe ruling is based the court states that at tbe bearing the petitioner asked for only a copy of said deed (c), waiving tbe copies.of tbe other two documents (a) and (b), and continued as follows:
“Copies of documents should be issued to persons who may have a right to them. If the petitioner in this case is not such a person as is mentioned in the first part of section 25 of the Notarial Law (Acts of 1914, page 146), he is among those mentioned in the second part, and there is no doubt that he complied with the requirement of that section by showing to the court the necessity for the issuance of the copy in a verified petition stating that the deed should form a part of the record in an action pending before the District Court of Arecibo to which he was an interested party.”
*255We do not agree with that reasoning. Section 25 cited by the conrt reads as follows:
“ Section 25. — The parties, their ancestors and successors in the subject matter of the contract and any person appearing as interested therein, may apply to and obtain from the notary copies of the original documents. Any other person may also obtain copies of a notarial document upon justified (sic) application to a district court, which in its reasonable discretion may issue an order to that effect. * * * ’ ’
The first part of the statute quoted authorizes the parties to a public document -and any other person interested therein to 'apply for and obtain from the notary a copy of the original document. And the second part allows any other person, though not a party or not interested in the document, to apply for and obtain a copy thereof by means of a substantiated petition to a district court, which, in its discretion, may issue an order to that effect.
We do not know whether in petitioning for the writ of mandamus the petitioner acted under the first or the second theory, and it was his duty to assume a frank and well defined position, as is required in every judicial controversy. If he acted under the first part of the statute he should have applied directly to the notary for the copy needed and, if refused, he then could petition the district court for a writ of mandamus to compel the notary to issue the copy, under section 1 of the Mandamus Act of March 12, 1903. According to that act, before a petition for a writ of mandamus may be considered the respondent must have denied a request to perform the act sought to be commanded of him; otherwise no right arises for petitioning the court for the writ of mandamus. Zavala et al. v. The Executive Council of Porto Rico, 9 P. R. R. 191. If the petitioner acted under the second part of the first paragraph of section 25, supra, the section itself provides that in order to obtain the copy he must present to the district court a substantiated petition and not a petition for a writ of mandamus. The authorization given *256by the district court to the notary to issue the copy is not an order or mandate for the issuance of it.
The petitioner has not followed the procedure prescribed by the law in either case and the writ of mandamus is not the proper means for obtaining the desired relief. The parties can not change the rules of procedure.
The judgment appealed from must be reversed and the petition for a writ of mandamus denied.
Reversed.
