Questione giuridica chiave
Whether the federal court could review the refusal to admit late factual submissions under cantonal procedure.
Decisione estratta
The challenge was not entertained because it did not specifically allege arbitrary application of cantonal procedural law.
Motivazione estratta
Whether new allegations are timely is primarily a matter of cantonal procedure; without a properly substantiated arbitrariness complaint, the federal court cannot examine the issue.
