I thought we were discussing the case of intercepting "external" vs. 
"internal" both of which require warrants (as opposed to stuff 
originating and finishing outside UK which requires no warrant at all - 
like all other countries AFAIK)

External stuff requires "certificated" warrants, and the Bassam letter 
and associated FIPR notes at http://www.fipr.org/rip/#Overlapping are 
all about how the wiggle room applies viz. (****)

/<<How do 8(3) and 15(3) interlock with clause 5(6)?/

Clause 5(6) allows, under the authority of an interception warrant, all 
such conduct as it is necessary to undertake in order to do what the 
warrant expressly authorises. This conduct can include the interception 
of communications - whether external or internal - not identified by the 
warrant. But such interception must be the minimum necessary to achieve 
the object of the warrant, and must be proportionate to that object. 
***** The clause applies equally to warrants complying with clause 8(1) 
and (3) *****. In the latter case it could, for example, make lawful the 
interception of internal communications where these mixed with external 
communications on a trunk used mainly for external purposes. 
Communications that originate and are received in the UK are always 
"internal"; as is well known, some of these will go abroad en route and 
so be carried on primarily external trunks. It is not possible to 
intercept the external communications on the trunk without intercepting 
the internal communications as well.>>
