Questão jurídica principal
Whether refusing to hear witnesses A.________, B.________, and C.________ violated the right to be heard.
Decisão extraída
No. The applicant had earlier opportunities to question the experts and to request additional evidence, and the lower courts could reject the requests through anticipatory assessment of evidence.
Fundamentação extraída
The witness requests were late, insufficiently substantiated, or aimed at matters already covered by prior expert evidence; the courts could consider the proposed testimony incapable of affecting the result.
