Actually there is another and perhaps rather amusing issue here:
"A person subject to a requirement under subsection (1)(b) to make a
disclosure of any information in an intelligible form [ie the recipient
of a s.49 notice] shall be taken to have complied with that requirement if—
(a) he makes, instead, a disclosure of any key to the protected
information that is in his possession; and [...]"
However, RIPA s.26
" (1) [...] “key”, in relation to any electronic data, means any key,
code, password, algorithm or other data the use of which (with or
without other keys)—
(a) allows access to the electronic data, or
(b) facilitates the putting of the data into an intelligible form; "
"(2) References in this Part to a person’s having information (including
a key to protected information) in his possession include references—
(a) to its being in the possession of a person who is under his control
so far as that information is concerned;
(b) to his having an immediate right of access to it, or an immediate
right to have it transmitted or otherwise supplied to him; [...]"
so make sure the Swiss lawyer only gives out keys at his discretion ...
[ as I understand this, Plod can then issue a s.49 notice. You reply
"the only key I have in my possession is the datum that the Swiss lawyer
may be able to supply a key."
You have then given them the only key in your possession, and complied
with the notice as defined in ss.50(2) - and they cannot then use the
notice to require you to do anything more, such as ask the Swiss lawyer
for the key, as you have already complied with the notice ]
I am not a lawyer ...
