Tokens: In
my
view
,
the
principle
of
effectiveness
underpins
and
is
enshrined
in
all
the
elements
of
the
balancing
exercise
,
not
only
in
the
balancing
test
itself
of
assessing
the
interference
with
the
right
,
but
also
in
the
two
sides
to
be
balanced
:
as
regards
the
right
,
it
helps
to
determine
and
protect
it
by
making
it
practically
effective
,
and
regarding
the
interference
,
it
helps
to
guarantee
that
the
measure
taken
will
appropriately
and
effectively
serve
the
aim
pursued
.
Therefore
,
lack
of
a
thorough
and
well
-
reasoned
balancing
exercise
may
affect
all
the
above
elements
,
but
even
if
it
affects
only
one
of
them
,
the
whole
machinery
of
the
balancing
exercise
may
be
rendered
ineffective
.
