Questão jurídica principal
Whether the appeal against the non-entry decision was admissible and what scope of review applied.
Decisão extraída
The appeal was admissible, but review of the non-entry decision was limited to whether the matter had to be sent back for material examination; a renewed extension of the permit could not be claimed because no valid permit remained in force.
Fundamentação extraída
A permit already finally refused cannot simply be extended again; only a new application or reconsideration request based on materially changed circumstances can justify renewed examination.
