14 While the OP is silent on this issue, the Subcommittee elaborated also in its Analytical Assessment Tool for NPMs that it should be clearly set forth in a new or existing constitutional or legislative text ‘that the national preventive mechanism is to be given a preventive mandate and powers in accordance with the Optional Protocol’.20 The SPT has further reiterated that having a legal basis for an NPM is ‘a prerequisite for its institutional stability and functional independence’.21 Also the SRT demands for a clear legal basis.22
(p. 895) 15 A clear constitutional or legislative basis specifying the NPM’s mandate and powers guarantees that an NPM has structural independence from all branches of state,23 above all from the executive branch,24 including the police, military, and other security forces. Hence, an NPM placed under the authority of a Ministry or administratively attached to a Ministry raises questions about its functional independence. While, in practice, this link can be purely formal and the NPM can act truly independently in reality, it puts the NPM in a situation of vulnerability. The SPT for example expressed concern about the office of one NPM being within the Ministry of Justice, from which it derives the human resources for its operation.25
16 The SPT envisages the provisions on the NPM to be found in a clear legal basis, may it be a separate law26 or clear provisions in existing legislation. A separate law is especially important for the perceived independence of an NPM that is part of an institution with an additional mandate, as appearance of partiality can be exacerbated by the lack of a separate legal basis.27 The Paris Principles28 have been interpreted by the OHCHR and ICHR to require a separate law,29and the SRT supported this solution.30
17 As to the content of legislation establishing the NPM, it is of fundamental importance that the requirement for an NPM’s legal basis includes ‘the fact of designating an existing institution to carry out the NPM mandate’.31 Such ‘anchoring’ of the NPM in legislation guarantees that the only authority with the ability to alter the existence of the (p. 896) NPM is the legislature itself32 while it cannot guarantee freedom from abuse, namely by the legislature.33 When the body designated as the NPM performs other functions in addition to those under the OP, an explicit designation of the body carrying out the NPM, eg the entire NHRI or the ombudsperson, prevents uncertainty regarding which institution fulfils the mandate of the NPM and hence inhibits weakening the efficiency and the institutional credibility of the NPM.34 Further, the relationship between the NPM function and the rest of the organization, the working methods and the safeguards applicable to preserve the independence of that function should be clearly set out in internal regulations.35
18 What clearly has to be set out in a constitutional or legislative text is the mandate and powers of the NPM.36 According to the SPT, this is to be done by ‘specifying the composition of the mechanism and its sphere of competence’.37 The SPT further elaborated in its Assessment Tool that, first, ‘[s]uch legislation should extend the visiting mandate to all places where people are or may be deprived of their liberty, as set out in article 4 of the Optional Protocol’.38 This wording should be taken over and an exhaustive list avoided as it could exclude certain new types of places of detention.
19 Second, with reference to Articles 19 and 20 OP, the SPT states that the legislative text should grant the NPM at minimum:39
(p. 897) 20 Third, as to the NPM’s mandate under Article 22 OP, the SPT notes that ‘[l]egislation should clearly state the obligation of competent authorities to examine the recommendations of the national preventive mechanism and to enter into a dialogue with it regarding the implementation of its recommendations’.43
21 Fourth, as to the obligation of the States parties to guarantee the functional independence of the NPMs according to Article 18(1) OP, the SPT notes that ‘[t]he relevant legislation should specify the period of office, whether determined or open-ended, of the members of the national preventive mechanism and any grounds for their dismissal’.44
22 Fifth, regarding the obligation of the States parties to guarantee the independence of the NPMs’ personnel according to Article 18(1) OP, the SPT states that
the legal basis should guarantee that the members of the national preventive mechanism and its staff enjoy such privileges and immunities as are necessary for the independent exercise of their functions,45 and should address the issue of reprisals and other such actions against members of the mechanism,46 their partners and any person who has communicated with the mechanism.47
The selection process for the members of the NPM should, according to the SPT, ‘preferably be prescribed in the governing NPM legislation’.48
23 When criticizing States parties for the lack or weak legal basis, the SPT has stipulated further recommendations on the content of NPM law. Regarding NPM membership, the SPT specifically recommended that the State party should enact specific legislative provisions setting out ‘appointment criteria and membership processes’.49 In another case, the SPT recommended that the law on the NPM ‘provide that membership of the NPM is incompatible with any other function which could affect its independence and impartiality’.50
24 Regarding the visits of NPMs, the SPT urged the State Party to ensure that the legal framework provides for ‘unrestricted access to all places of detention’.51 Moreover, ‘the State party should guarantee in law and in practice the full mandate of the NPM, in particular its right to conduct private interviews with persons deprived of liberty’.52 The NPM’s legal framework should also outline privileges and immunities of ‘those who contribute to the NPM, including experts and civil society’.53 The legal framework should furthermore guarantee ‘protection for persons who provide information to the NPM’.54
(p. 898) 25 Budgetary issues should also be regulated directly in the NPM law. As to Article 18 OP, the NPM’s legal framework should, in order to ensure its continuous financial and operational autonomy, ‘require a separate budget line in the State budget for the funding of the NPM’.55 On budgetary issues, the SPT deems it important to specify in the legislative provisions that the NPM will be allocated sufficient additional resources to enable it to fulfil its functions.56 It is also suggested that the source and nature of the NPMs’ funding be specified in their founding instruments.57
26 Similarly, the SPT suggested that the NPM law should mention the obligations of the State party to present and discuss the annual reports in the national legislative assembly.58
27 Finally, the SPT noted that the State party should ‘guarantee in law and in practice the full mandate of the NPM, in particular … to maintain direct contact with the SPT, in order, inter alia, to follow up on compliance with the present recommendations’.59
28 The NPM legislation has to be adapted to the national circumstances with the aim of an effectively functioning NPM.60 The SPT’s satisfaction with the NPM law in Paraguay61 and Honduras62 may be referred to here. Also some other NPM laws provide models on certain provisions, eg giving broader powers than required by the OPCAT63 or containing a provision that resemble the provisions of the OPCAT.64
