"proveido" is a decision taken by the court on any matter of "mero trámite" (i.e., decisions that merely keep the process moving, without actually resolving the dispute).

A "proveido" is "firme y consentido*" once the legal deadline for all forms of appeals against it has passed.

* Chile: "firme y ejecutoriado"

To my knowledge, it is sufficient in English to say that the decision is "firm".

La redacción no es clara, pero parecería ser "que a la fecha se encuentre consentido" indica que las partes no han apelado dentro del plazo que tenían para hacerlo, por lo que han dado consentimiento tácito a la decisión judicial.

Dear Robin, I don't think I omitted translating "proveído". Let's see it this way: if the parties "have not appealed", it is clear that they have not filed a remedy against the decision ("proveído"). We could add the word 'decision' to make the meaning clearer (though it is implicit in my answer): "the legal term having expired without the parties having appealed the decision as of this date".

This is how I understand it. I take "consented" in this context as meaning "stipulated to" (i.e., "agreed to").
