By the time California's first constitution was drafted in 1849, the Gold Rush had already transformed the state's Spanish-speakers into a minority (13,000 of nearly 100,000 residents). Without opposition, however, delegates to California's Constitutional convention in 1849 approved an important recognition of Spanish language rights:

"All laws, decrees, regulations, and provisions emanating from any of the three supreme powers of this State, which from their nature require publication, shall be published in English and Spanish." So it seems the tradition California's founding fathers had in 1849 a different idea [http://www.languagepolicy.net/archives/1879con.htm].

Mr. Ayers who represented the Los Angeles area testified in 1849 testified :"Mr. AYERS. ... In the section of the State which I represent [Los Angeles County] there are large portions of it which are entirely populated by a Spanish-American population, not a foreign population, but a population who were here before we were here, and I wish to say that almost without an exceptional instance these natives of California, who were adults at the time this State was ceded to the United States by Mexico, are still in the same condition, as far as their knowledge of English is concerned. There are but very few of them, if any, who understand our language at all, and, if I am not mistaken, in the treaty of Guadalupe Hidalgo there was an assurance that the natives should continue to enjoy the rights and privileges they did under their former Government, and there was an implied contract that they should be governed as they were before. It was in this spirit that the laws were printed in Spanish.
.
One of the other delegates [a Judge Rolfe from San Bernardino] saied, "there are townships in Southern California which are entirely Spanish, or Spanish-American. ... [I]t would be wrong, it seems to me, for this Convention to prevent these people from transacting their local business in their own language. It does no harm to Americans, and I think they should be permitted to do so... .This is not a question of demagogism, or partisanism; it is a question of right. Now, I know that in Southern California there are districts and communities that are so entirely Spanish that if you deprive them of the right to continue their proceedings in Justices' Courts in Spanish, you will deprive them of justice".

Kinda suggests the Spanish language is part of the fabric of what California was founded on?? It seems if Ayers is right, then to impose in the acquired territories under that Treaty an English Only rule, would violate that law??
.
What says you??

Taking this further, are we denying as Ayers suggests, depriving the Spanish speaking only population of justice by English only courtrooms?
