Questão jurídica principal
Whether the respondent should be excluded as a party and whether it has party status in the proceedings.
Decisão extraída
The respondent properly had party status because its rights and duties were directly affected by the proceedings; exclusion was unwarranted.
Fundamentação extraída
Under Art. 6 VwVG, persons whose rights or obligations are affected are parties. The respondent still held the operating permit and retained lease/overflight rights, so it was directly affected.
