“Your failure to pay National Insurance contributions as a non-employed person for the period1 September 1955 to31 May 1964 within the prescribed period is attributable to your ignorance or error, however, that ignorance or error was due to the failure on your part to exercise due care and diligence. Accordingly, you are not entitled to pay contributions as a non-employed person for the period1 September 1955 to31 May 1964 .”
“Where a person was entitled to pay a contribution....... but he failed to pay that contribution in the period provided for payment.... and his failure is shown to the satisfaction of the Secretary of State to be attributable to ignorance or error on his part which was not due to any failure on his part to exercise due care and diligence, that contribution may be paid within such further period as the Secretary of State may direct.”
“There are SPECIAL CONTRIBUTION PROVISIONS for:- Men age 65 and under 70 who have retired or men age 70 and over – see Leaflet N.I.40. Men in casual or subsidiary employment or employed only to an inconsiderable extent – see Leaflet N.I. 37. Men paid at a weekly rate of 30s. or less and not receiving board and lodging – see Leaflet N.I. 40. Self-employed and non-employed men whose income does not exceed£104 a year – see Leaflet N.I.27. Men who go abroad – see Leaflet N.I.38. These leaflets can be obtained at any local Pensions and National Insurance Office.”
“Exercising due diligence involves the positive step of making enquiries. Mr Williams contended that while the National Insurance authorities try to keep a contributor informed of what he needs to know to maintain his contribution record, it can do this effectively only if the contributor personally contacts them. The Appellant had failed to make any enquiries and therefore had not exercised due diligence. ... If she had never heard of National Insurance I would readily agree that it could not be said that she had failed to exercise due care and diligence if she had made no enquiries about it. However, she was not ignorant about the existence of the NI scheme and must have known the basic principle that benefits were in some way related to contributions. ... I follow the principle in Walsh that she should have made some enquiries. I entirely accept Mr Adojutelegan’s point that the facts here are not comparable to that case as she was living abroad and so it was harder to make enquiries. But it was not impossible. ... Doing nothing is not the exercise of due care and diligence. Had she made an enquiry she would have been told there was a six-year time limit for paying contributions. Her ignorance of this was due to her failure to make enquiries, which is a failure to exercise due care and diligence.”
“The evidence is that Dr Rose was aware at the time of his choices, or at least he would have been aware of them had he read the leaflets he was sent and had he made the reasonable enquiries that those leaflets should have prompted. He chose at that time not to enquire or not to pay. In the current context of the current question of protecting his NI record, he chose not to exercise due care and diligence in protecting his contribution record.”
“I would observe that the result in this case should not be thought to reduce the importance of the duties imposed on those who are liable to pay NIC’s or who have the option to do so. Ignorance is not an excuse save in limited circumstances. It is a person’s own responsibility to pay NIC’s and, if he or she fails to do so at the right time, he or she may lose the chance to pay them later on the basis of ignorance at the appropriate time of the need to pay. The facts of this case are unusual, and, while of course this judgment deals only with this appeal, I would observe that facts like these may not often occur.”
“...to treat all relevant circumstances as factors which have to be balanced together to reach an assessment or evaluation on a case-by-case basis as to whether due care and diligence was exercised and, if not, whether the failure was the cause of the contributor’s ignorance...”
“... I do not think it is possible to produce a definitive list of relevant factors. However, they would include the contributor’s age and any relevant physical disability or incapacitation. Thus [counsel for HMRC] accepted that a 19-year-old student might be in a stronger position to show that he had exercised due care and diligence when he took no action to pay contributions than an older person in employment.... Knowledge of the NIC scheme is also likely to be a very important factor, but it may have to be established what the source of his knowledge was and generally the degree of knowledge.... The decision-maker also has to look at the circumstances as they stood at the time....”
