My Lords, my noble friend Lady Hamwee and I have Amendments 37, 121, 153 and 161 in this group. Basically, these amendments relate to Clause 20, “Grounds on which warrants may be issued by Secretary of State”. We suggest an additional paragraph, where a warrant is issued for the purposes of preventing or detecting a serious crime, or in the interests of the economic well-being of the UK,
“only where there is a reasonable suspicion that a serious criminal offence has been or is likely to be committed”.
I refer to the briefing provided by Liberty, which points out that one of the greatest problems, recurrent in every power in the Bill, is the lack of a reasonable suspicion threshold for surveillance warrants to be authorised for the purposes of preventing and detecting crime. It states that:
“Intrusive powers can be authorised in order to ‘prevent and detect serious crime’, or even (in the case of communications data) to collect tax, prevent disorder, or in the interests of public safety. However, these general purposes are left wide open to broad interpretation and abuse without requiring a threshold of suspicion”.
The briefing says that a requirement of reasonable suspicion, when the purpose to prevent and detect serious crime is invoked, would prevent the potential abusive surveillance of law-abiding citizens that has regrettably been seen in the past.
The threshold of reasonable suspicion has long been an important safeguard for citizens and law enforcers against the risk of arbitrary use of police powers. The necessary and proportionate standard invokes an important assessment of the extent of the intrusion, but it does not, as we read it, require a burden of proof. Perhaps the Minister could explain how or why the “reasonable suspicion” test should not be applied to the various powers covered in our amendments. I beg to move.
