Key legal question
Whether the refusal to hear additional witnesses violated the appellants' right to be heard.
Extracted holding
Yes. The lower court did not explain why the proposed testimony could not affect its assessment, although the witnesses could have clarified company practice and safety compliance.
Extracted reasoning
Under Art. 29(2) BV, relevant evidence must be taken unless the court may, on non-arbitrary anticipatory assessment, conclude it would not change its view. The offered witnesses were capable of affecting the factual picture.
