Tokens: No
provision
of
domestic
law
,
however
,
lays
down
any
limits
on
the
exercise
of
those
powers
.
Thus
,
for
instance
,
the
aforesaid
Law
does
not
define
the
kind
of
information
that
may
be
recorded
,
the
categories
of
people
against
whom
surveillance
measures
such
as
gathering
and
keeping
information
may
be
taken
,
the
circumstances
in
which
such
measures
may
be
taken
or
the
procedure
to
be
followed
.
Similarly
,
the
Law
does
not
lay
down
limits
on
the
age
of
information
held
or
the
length
of
time
for
which
it
may
be
kept
.
