The core conflict faced by the Panel of Judges was the legal interpretation of the juridical nature of the application return letter. The DJP maintained that the letter was merely a formal notification indicating incomplete requirements, not a definitive, final, and binding Decree (Surat Keputusan or SK) (beschikking). In other words, the letter simply returned the application to the Taxpayer for correction, rather than substantively rejecting the request. Therefore, the DJP argued that the letter was not the object of a lawsuit regulated under Article 23 paragraph (2) of the UU PP, which refers to a "decision" that constitutes a rejection of an application.
In its resolution, the Panel of Judges firmly ruled in favor of the DJP's argument. The Panel stated that according to Article 36 paragraph (4) of the General Provisions and Tax Procedures Law (UU KUP), the decision on an application for the Cancellation of an Incorrect SKP must be issued in the form of a Surat Keputusan (SK). Since the object of the dispute was a notification letter returning the application and not a formal Decree of rejection, the object was deemed not to meet the formal requirements as an appealable decision. Consequently, the Panel granted the Motion to not examine the merits of the case and declared the lawsuit Inadmissible (Inadmissible or Niet Ontvankelijke Verklaard).
The implication of this decision significantly impacts the Taxpayer's litigation strategy. This ruling serves as important jurisprudence affirming that formal administrative actions that are not final decisions, such as a letter returning an application due to incomplete requirements, cannot be the basis for a lawsuit at the Tax Court. Taxpayers are strongly advised to focus efforts on formal rectification rather than incurring time and expense by filing a formally defective lawsuit. Absolute adherence to the formal requirements stipulated in the relevant Minister of Finance Regulation (PMK) is the most effective preventive measure to ensure an application can be processed until a valid Decree is issued, which then becomes a legitimate object of dispute.
