Apes are People too !

Actually it should do. The laws are meant to give the apes the same rights as a minor, so they wouldn't be able to work (or they would within whatever child labour laws exist).

Well, right now it seems to be more about defending their interests than integrating them into society. I don't think they will be capable of understanding the law in its entirety (who knows, maybe they'll get the gist though), so we can't ask them to abide by it. We can't send the apes to school since the difference between human kids and apes is that human kids will not always be considered minors.

Given the wording as I've seen it, euthanasia laws would apply (does the law of that particular country allow the mentally disabled/minors to be euthanatized?).

I believe so, since they would be minors they wouldn't be able to give informed consent to the tests. More information can be found at their website, here is their declaration. This isn't the Spanish Socialist Party's site, but I believe it shares the same kind of views, and may be the influence for the proposition.
