Rule breakdown
Submit a complete and consistent application
The application must be complete and accompanied by the requisite documents. A deficiency can arise from a defect, a missing relevant document or inconsistency with the understanding reached in a pre-filing consultation.
Reconcile the form, transaction scope and attachments before filing. If consultation occurred, explain relevant changes rather than allowing unexplained inconsistencies.
The authority’s notice has a month-end clock
The relevant authority serves a deficiency letter within one month from the end of the month in which the application is received.
For example, receipt during April gives a notice period measured from April’s end. This is different from the applicant’s response clock, which runs from actual receipt of the letter.
Correct within thirty days of receiving the letter
The applicant must remove the deficiency or modify the application within thirty days of receipt. Preserve the receipt evidence and address each identified issue with the required documents or revision.
Do not measure this period from the date the team internally forwards the notice to an adviser.
An uncorrected defect can stop the application
The authority may order that the application not be allowed to proceed if the defect is not removed as required. A reasonable opportunity of being heard must be given before that order.
Use the hearing to address the actual deficiency and supporting evidence; do not assume an incomplete file progresses automatically.
The specified refusal outcome carries a refund
Where the application is not allowed to proceed under sub-rule (5), sub-rule (7) requires refund of the fee paid. This is a specific outcome and differs from voluntary withdrawal under Rule 107.
Retain the order and fee-payment evidence so the outcome and refund can be reconciled accurately.
Key takeaways
Complete Form 51 and attachments
Missing or inconsistent material can trigger a notice.
Thirty-day correction
Measure from receipt of the deficiency letter.
Hearing before refusal
The specified order requires a reasonable hearing.
Outcome-specific refund
The sub-rule (5) refusal carries the stated refund.
Practical checklist
- Reconcile the form and every attachment.
- Record receipt and calculate the thirty-day response period.
- Answer each deficiency and retain hearing submissions.
Avoid
- Do not confuse the authority’s month-end clock with the applicant’s receipt-based clock.
- Do not apply the refund provision to a different outcome without checking its rule.
