What if SC declares Php1000 CHR budget UNCONSTITUTIONAL; Budget re-enacted

In our previous posts, we explored the legal possibility of having the 1000-peso budget given to the Commission on Human Rights (CHR) by Congress for its 2018 operations:

[1] 1,000-peso CHR budget may be UNCONSTITUTIONAL; Separation of powers
[2] CHR constructively ABOLISHED thru budget; Congress cannot abolish CONSTI. body

Now, hypothetically, the Supreme Court declares allocation unconstitutional either because of the doctrine of separation of powers or because of the fact that said budget is a constructive abolition of a constitutional body, which cannot be done by Congress, what would happen to CHR's budget? The answer seems to be absent from the pages of the Constitution. Nevertheless, by analogy, we can apply Section 25 (Par. 7) of Article VI of the 1987 Constitution which provides:

"If, by the end of any fiscal year, the Congress shall have failed to pass the general appropriations bill for the ensuing fiscal year, the general appropriations law for the preceding fiscal year shall be deemed re-enacted and shall remain in force and effect until the general appropriations bill is passed by the Congress."

Hence, if the Supreme Court finds enough reason to declare this 1000-pesos budget unconstitutional, CHR's budget in the previous fiscal year should be considered re-enacted.
Quoted below is the part of the Constitution creating the Commission.
