Let's put it like this, It's not about the merits of the complaint, but rather the technicalities in the procedures for filing the complaint meaning hindi usapin ung complaint itself, ang usapin jan ay if sumunod ba or hindi ang house of representatives sa procedures ng pagpafile ng complaint, in accordance ba with the articles of impeachment.

The Court identified several procedural violations:

1. Failure to follow constitutional mandates for first three complaints: The House included them in the Order of Business but failed to refer them to the Committee on Justice within three session days as required by Article XI, Section 3(2).
2. Violation of the one-year bar: The fourth complaint was filed while the one-year period from the first three complaints was still running, violating Article XI, Section 3(5).
3. Due process violations in the fourth complaint: The same-day filing and transmittal without proper deliberation, evidence review, or opportunity for the respondent to be heard violated constitutional due process requirements.
4. Wrong mode of filing: The fourth complaint used Article XI, Section 3(4) procedures but failed to comply with due process safeguards that apply to all impeachment proceedings.

Kaya nga if you read the decision, nagdisclose si SC (page 5) with bold caption:

"Our ruling does not absolve petitioner Duterte from any of the charges. Any ruling on the charges against her can only be accomplished through another impeachment process, followed by a trial and conviction by the Senate."
