The case began when PT JBE filed a lawsuit, not because they disagreed with the tax calculation, but because they questioned "who" signed the rejection letter from the Directorate General of Taxes (DGT). The Plaintiff argued that the Director General of Taxes' Letter they received was legally defective. The reason sounds theoretically logical: the official signing the letter acted merely based on an internal delegation of authority (KEP-206/PJ/2021), which, according to the Plaintiff, should not bind the Taxpayer externally.
The Plaintiff insisted that the DGT's internal rules (beleidsregel) cannot serve as the legal basis for issuing decisions affecting Taxpayer rights. This is a classic argument in State Administrative Law attempting to rigidly separate internal policy rules from general binding regulations.
Conversely, the Defendant (DGT) argued that authority delegation is an absolute necessity for modern organizations and is protected by the Law on Government Administration. Without authority delegation, the Director General of Taxes would have to sign millions of letters alone—a bureaucratic impossibility.
The Panel of Judges VIII-A of the Tax Court took a firm, pragmatic stance. They rejected the Plaintiff's argument. In their considerations, the Judges asserted that although authority delegation rules are administrative-internal, they possess "legal relevance" that binds externally when executed. This means the signature of the mandated official is valid and equivalent to the mandator's signature. The Judges saw that if the Plaintiff's argument were accepted, the entire tax administration system could be paralyzed due to legal uncertainty over millions of documents signed by delegated officials.
This decision reinforces the doctrine that authority delegation within the DGT is valid and legally binding. For Taxpayers, this serves as a vital signal: do not waste excessive energy attacking the formal aspect of signatory authority unless there is a clear abuse of power. Focus on the substance of your tax dispute. Victory in the Tax Court is more often achieved through strong material evidence rather than narrow procedural loopholes.
