Key legal question
Whether the constitutional complaint met the reasoning requirements and showed arbitrariness or a breach of the right to be heard regarding rejected evidence in the B. case.
Extracted holding
The complaint was insufficiently reasoned and showed no arbitrariness or violation of the right to be heard; the evidentiary refusals stood.
Extracted reasoning
The arguments were merely appellatory. The lower court could, without arbitrariness, find the requested evidence incapable of creating serious doubt about authorship or the need for expert evidence.
