Proceedings held on holidays are:

Unless explicitly prohibited by a specific statute or rule, proceedings held on holidays are generally considered Valid. The validity of judicial or quasi-judicial proceedings primarily depends on adherence to due process and proper conduct, rather than the specific day of the week on which they occur. Legal systems prioritize the administration of justice.

• Prohibited is incorrect unless a specific law forbids it.
• Conditionally valid is too vague; while some conditions might apply, the default is usually valid.
• Re-inquired is not a standard consequence solely due to a holiday.
