Here's an excerpt in Spanish and English, from a Website comparing Mexican and US law. You might find it useful for other terms you are seeking. I'm also giving you the URL for the Alta Vista search results for "fuero común" IN ENGLISH (so I could locate texts with both English and Spanish--a good trick when you're trying to find a term *in context*)

3. Criminal Code (Código Penal) (1931)

Mexico's substantive criminal laws are very similar to those of the United States. Vargas, supra, comments that there are a few differences in emphasis—particularly in the areas of sentencing and
drugs—but otherwise the Mexican Criminal Code is not significantly different from the codified criminal laws in the United States. The Criminal Code for the Federal District, the model for all corresponding state codes, has not been amended significantly since its adoption in 1931.
