The controversy which surrounds intercept evidence is far-reaching and very complex.  This debate is not contained within the courtroom but also spans wider principles of legal justice and the rules which uphold democratic law. Even countries which currently allow this evidence, such as certain US states [1] , have noted that it can be difficult to use successfully and without violating past Acts and wider legal principles [2] . Bodies such as MI5, MI6 and GCHQ argue that revealing the ‘evidence’ necessitates revealing how that evidence was garnered; as such, intercept evidence can compromise the security status of intelligence services and their techniques [3] . This kind of method should be reserved, if used at all, for singular, extreme cases such as terrorist activity where all other possibilities for collecting evidence have truly been exhausted. Finally, wiretapping and intercept evidence has been criticised or deemed illegitimate by many legal professionals [4] [5] . For this kind of evidence to be admissible in court, it needs to follow legal principles which have already been set up. There is little evidence that it can do so.
