From Paper done by Robert McDougall for his Third-Year at Drake High-School,
Victoria, Columbia: Canadian Commonwealth, 1995

..."California English" is basically standard English with a lot of Spanish loan-words, pronunciations, and grammatical tendencies (actually, as it is, there are several hundred Spanish words in English as spoken in Canada). Language is actually kinda a muddle in the Republic of California. Originally, California's "official" language was Spanish (not that they Officially declared it to be such, that's just what most people spoke). As more and more English speakers moved in, legislation (since things were organized enough for such by then) declared it to be officially Bilingual in 1880 or so.

The "upper classes" in California then and now tend to speak either pure Spanish (Castilian preferred) or pure English (RP, of course) and look down their noses at anyone who "mangled" either tongue. The majority of the people, naturally, didn't care one way or another and tend to use either English or Spanish, intermixed, depending on how they felt/what they were saying.

This went on unofficially for years, with no real standardization, until the 1930's, when California suffered a major rise of patriotic pride and decided that they should have their own language, separate from the Mexicans and Texans and Canadians. And after a couple of decades of fiddling around (mostly, trying to hit an ever moving target), the California Language Board came out with their first "approved" Californian English dictionary and grammar. And they have updated it every five years since.

By this time, of course, things were running on pure bureaucratic inertia, the impetus for California to have its "own" language had long ago slumped. So Monterey, rather than making Californian English the "Official National Tongue," simply added it to the other two as officially recognized languages and the Republic became trilingual.

C+ Nice start, but try and show proof of your statements...Footnotes! Of course, Californian English as spoken does vary quite a bit from as written (not the least bit helped by the conservative nature of the Board) and written Californian English remains in many ways an "artificial" tongue - like Esperanto, but with a larger number of "Books In Print." Really, California runs on four languages, not three: Spanish, English, Official Californian English, and the vast ever-changing morass that is spoken California English. There are some signs that this is beginning to end, as spoken and written versions of C.E. are converging (due to years of teaching the written to the speakers of it, and Board Members being replaced by people who actually speak Californian English), but it'll probably take years. And, as has often been pointed out, spoken and written real English often don't agree!...
