The guilt of the appellant of the crime of falsification of a public  document with which he was chadfrged is fully and conclusively established not only by the testimony of the witnesses for the prosecution, but by his extrajudicial written admission of the facts constituting the offense and his admissions on the witness stand testifying in his own behalf.

The statement of the accused that he falsified the document in question at the suggestion and request of the presidente of the  town of  which he was treasurer was formally denied by that official; and, even if it were true, it in  no wise relieves the accused of his criminal responsibility.

The sentence imposed by the trial court is in strict conformity with the provisions of the Penal Code, defining and penalizing the crime of which  the appellant is convicted, except in so far as it imposes subsidiary imprisonment in case of insolvency and failure to pay the fine imposed of 1,250 pesetas.  Article 51 of the Penal Code expressly  provides that subsidiary  personal liability on account of insolvency shall not be imposed upon a person condemned to a penalty higher in the general scale than that of presidio correctional.   The principal penalty imposed in this case is that of fourteen year eight months and one day of cadena temporal.  The sentence imposed by the trial court should, therefore, be modified by omitting therefrom so much thereof as undertakes to impose subsidiary imprisonment in case of insolvency and failure to pay the fine, and, thus modified, it should be and is hereby affirmed with the costs of this instance against the appellant.  So ordered.
