Section 13
SEC. 13. Any person who under such compulsion as would otherwise excuse him offends against either of the last two preceding sections shall not be excused thereby, unless within the periods hereinafter stated he declares the same, and what he knows touching the same, and the persons by whom such oath or obligation or engagement was administered or taken, by information upon oath before a justice of the peace, judge of a Court of First Instance, or provincial fiscal of the municipality or province in which such oath or engagement was administered or taken. Such declaration may be made by him within fourteen days after the commission of the offense, or, if he is hindered from making it by actual force or sickness, then within eight days after cessation of such hindrance, or on his trial, if that happens before the expiration of either of those periods.
