HC allowed petition - Assessing officer's order violated principles of natural justice by denying opportunity to petitioner to present defense - Failure to serve show cause notice rendered proceedings flawed - Appeal remedy denied due to delay caused by lack of knowledge of order - Procedural requirements mandatory, non-compliance invalidates actions - Fair opportunity must be given to all parties - Appeal timelines to consider actual knowledge of orders - Assessing officer's order treated as show cause notice to enable petitioner to file objections.
