"On the26th February 2010 we received instructions to make a BACs transfer to HMRC in the sum of£18,848.24 . For operational/security reasons on our part this was divided into two tranches and the payment made on that date. We understand that whilst the sum of£8,848.24 was received by you on or before 28th February the remaining£10,000 is logged at 2nd March. The payment was one transaction and we understand this anomaly has caused the financial penalty to be imposed. On behalf of our customer we ask for a review on the grounds that these circumstances have arisen through our Banking system procedures and that the charge may therefore be properly removed."
" For all the purposes of this Act, a person shall be deemed not to have failed to do anything required to be done within a limited time if he did it within such further time, if any, as the Board or the [tribunal] or officer concerned may have allowed; and 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."
