Write a professional blog article for a Tax Consultant firm's website.

Context: GSTN has removed the portal restriction that prevented taxpayers from filing appeals where a demand order reflected NIL or Zero demand, despite an underlying liability dispute and payment having been made before issuance of the order.

Taxpayers facing such cases can now file an appeal in Form GST APL-01 against these orders. For any difficulty in filing, taxpayers may raise a ticket with the GST Helpdesk.

- Use the researched details to write an accurate, well-informed article. Do NOT rely solely on the context above — verify and expand with real, current information
- Do NOT hallucinate or make up any information — every fact, date, section number, and rule must be verifiable
