“As a general rule, when a court or tribunal is asked to extend a relevant time limit, the court or tribunal asks itself the following questions: (1) what is the purpose of the time limit? (2) how long was the delay? (3) is there a good explanation for the delay? (4) what will be the consequences for the parties of an extension of time? and (5) what will be the consequences for the parties of a refusal to extend time? The court or tribunal then makes its decision in the light of the answers to those questions.”
“…where a person had a reasonable excuse for not doing anything required to be done he shall be deemed not to have failed to do it unless the excuse ceased and, after the excuse ceased, he shall be deemed not to have failed to do it if he did it without unreasonable delay after the excuse had ceased.”
“I cannot take the view that the failings of a professional agent can ordinarily be considered objectively reasonable as an excuse. If that was the position, then professional agents would be able to ignore deadlines for filing or undertaking other tasks safe in the knowledge that their clients could not be penalised because the clients would simply point to the failings of their various professional agents.”
“If a taxpayer claims that his accountant has been negligent, for example, by failing to meet a deadline for filing a return or undertaking some or other administrative task, then the negligence of the accountant will not usually provide a defence to a penalty because the accountant is simply acting as the taxpayer's agent or functionary in filing the document that needs to be filed by a particular deadline. In other words, he is acting as an agent or functionary for his principal; but not as an independent professional adviser. However, in a situation where a professional adviser is not retained simply to act as a functionary, but is retained to give professional advice based upon the best of his skill and professional ability, he is not then a functionary or agent for his principal. He is a professional person acting under a retainer to give professional advice upon an identified issue. He is bound to provide that advice to the best of his professional skill and ability, whilst taking reasonable care in and about preparing and giving that advice. In other words, he is acting as a true professional, rather than as an agent or functionary.”
