A government department loses your application documents and tells you to reapply from the beginning.
This argument places the consequence of the department's own failure onto you. The department lost your documents through their own administrative failure — but demands that you bear the cost in time, money, and queue position. The logical flaw is that the party who created the problem is asking the other party to fix it. This is procedurally unfair and potentially reviewable under administrative law.
After you respond, they may push back with these arguments. Members get the full rebuttal for each.
