“If other means of redress are ‘conveniently and effectively’ available to a party, they ought ordinarily to be used before resort to judicial review: per Lord Bingham of Cornhill in Kay v Lambeth London Borough Council[2006] 2 AC 465 , para 30. It is only in a most exceptional case that a court will entertain an application for judicial review if other means of redress are conveniently and effectively available. This principle applies with particular force where Parliament has enacted a statutory scheme that enables persons against whom decisions are made and actions taken to refer the matter to a specialist tribunal... To allow a claim for judicial review to proceed in circumstances where there is a statutory procedure for contesting the decision risks undermining the will of Parliament.”
“A decision mentioned in sub-paragraph (i), (ii) or (iii) of section 38(1)(d) [i.e. a decision to designate in the first instance] may not be questioned by way of proceedings for judicial review (and nor may a decision to which section 38 applies)”
“It is possible that some who have been protesting legitimately under the banner of PA will be deterred from continuing to protest for fear of incurring criminal liability (for example on the basis that continuing their protest might be perceived as expressing support for PA or as organising on its behalf). The evidence I have seen establishes that the broad criminal prohibitions imposed by the 2000 Act, and the very long sentences potentially available for breach of them, can cast a long shadow over legitimate speech. This, however, is the inherent consequence of a regime which aims to disrupt and disable organisations which meet the threshold for proscription and which the Secretary of State and Parliament decide to proscribe.”
“Did Parliament intend that the Home Secretary should be permitted to exercise her conferred power for the purpose of proscribing an organisation that satisfied the section 1 TA definition, but: (i) whom the Home Secretary accepts does not advocate violence; (ii) the vast majority of whose actions were assessed by JTAC [the Joint Terrorism Analysis Centre] and PRG [the Proscription Review Group] to be lawful; (iii) whose protests are directed at preventing acts widely recognised as atrocity crimes and breaches of international law (including by the Foreign Secretary himself; (iv) which enjoys widespread and justifiable popular support; (v) where proscription would cause support for those lawful actions to be punishable by up to 14 years’ imprisonment; (vi) where ‘civil disobedience on conscientious grounds has a long and honourable history in this country’ (Fn: R v Jones (Margaret)[2006] UKHL 16 ,[2007] 1 AC 136 , [89]); and (vii) as this Court appeared to accept, where proscription may have adverse consequences ‘for public confidence in the regime of the 2000 Act’ (interim relief judgment, [53])?”
“An action done for the purposes set out in s. 1(1)(b) and (c) constitutes terrorism if it involves serious damage to property even if it does not involve violence against any person or endanger life or create a risk to health or safety… [T]his definition of ‘terrorism’ makes the statutory concept wider than the colloquial meaning of the word.”
