‘“Unreasonable” also means what it has been understood to mean in this context for at least half a century. The expression aptly describes conduct which is vexatious, designed to harass the other side rather than advance the resolution of the case, and it makes no difference that the conduct is the product of excessive zeal and not improper motive. But conduct cannot be described as unreasonable simply because it leads in the event to an unsuccessful result or because other more cautious legal representatives would have acted differently. The acid test is whether the conduct permits of a reasonable explanation. If so, the course adopted may be regarded as optimistic and as reflecting on a practitioner's judgment, but it is not unreasonable.’ 1 McPherson concerned a provision equivalent to rule 10(1)(b). LW v Hertfordshire County Council (SEN)[2019] UKUT 109 (AAC) 7 HS/773/2018 9 In MG v Cambridgeshire County Council [SEN] [2017] AACR 35, an appeal to the Upper Tribunal concerning a legally aided appellant seeking costs against the LA, Upper Tribunal Judge Rowley stated in passing that First-tier Tribunals that they should apply considerable restraint when considering an application for costs under rule 10. Orders should be the exception, not the rule and should be made only in the most obvious cases. Judge Rowley considered that it was ‘crucially important … to begin by emphasising that nothing in this decision should be taken as encouraging applications for costs. The general rule in this jurisdiction is that there should be no order for costs. Tribunal proceedings should be as brief, straightforward and informal as possible. And it is crucial that parties should not be deterred from bringing or defending appeals through fear of an application for costs’ [26] 10 Whilst there is much to agree with in that statement, there are caveats.Before the Tribunals, Courts and Enforcement Act 2007 , special educational needs decisions from a local education authority were heard by way of judicial review in the High Court. It was not a cost-free regime. Parliament chose to continue the power to award costs when these cases moved to the tribunal system. There is no direct comparison with social security cases [now in the First-tier Tribunal (Social Entitlement Chamber)] where there has never been a power to award costs. The power to award costs in special educational needs cases should certainly be used sparingly lest ordinary people are frozen out of the specialist justice forum that tribunals uniquely provide. It generally will be inappropriate in a jurisdiction such this, where parents will often be acting on their own or with representatives who are not legally qualified, to encourage satellite applications for costs. But there will inevitably be cases in which the one side or the other abuses the generosity of the system. It is for these that a Tribunal’s discretionary power to award costs should be reserved. Three stage approach to deciding whether to make an award 11 The three basic steps in determining whether a costs order should be made are (i) Determine whether the party against whom an order for costs is sought has acted unreasonably; (ii) If it did, should the Tribunal make an order for costs? (iii) If so, how much. 12 It is important to bear in mind that the issue is whether the conduct was unreasonable, and not the withdrawal per se. Withdrawing an appeal may well be reasonable, depending on the circumstances. The salient circumstances were these: The F-tT’s decision was in January 2018. LW appealed. The main platform of the appeal was that she was denied a fair hearing because Mr O’
