“… [The Secretary of State] concedes that the said decision should be quashed on the ground that the … Inspector erred in law by misinterpreting condition 11 as requiring a scheme for only one affordable housing unit, when the description of the development in the original outline planning permission showed that three units were required”
“i) On an application for relief from a sanction underCPR 3.9 , it is usually appropriate to start by considering the nature of the non-compliance. If the non-compliance can be regarded as trivial or insignificant, the court will usually grant relief provided that an application is made promptly [40]. ii) If the non-compliance cannot be so regarded, the court should consider why it occurred and will still be likely to grant relief if there is a good reason for it [41]. iii) Good reasons are likely to arise from circumstances outside the control of the party in default [43]; by contrast, inefficiency or incompetence of a party's solicitors – for example, where a deadline is simply overlooked – is unlikely to amount to a good reason [41]. iv) Where the non-compliance is not trivial and there is no good reason for it, the court is still required byCPR 3.9 to consider “all the circumstances of the case, so as to enable it to deal justly with the application” [37] + [49]. However, relief should not usually be granted in such cases because the circumstances which should generally be given greatest weight are the two factors specifically mentioned in the rules [49] + [58].”
