Human Rights Acts and the principle
of parliamentary sovereignty
The principle of parliamentary sovereignty as
explained by Dicey guarantees Parliament, as
the democratically elected body, the right to
‘make or unmake any law’ and obliges courts to
‘uphold and enforce it’.15
Parliamentary sovereignty is maintained through
a Human Rights Act based on the dialogue
model in several ways. First, if Parliament wishes,
it is able to pass laws that contravene human
rights, in line with its democratic mandate.
If it chooses to do so, then it must publicly
justify why through parliamentary processes.
Secondly, the judiciary must interpret legislation
consistently with Parliament’s intent. Thirdly,
the judiciary cannot invalidate legislation for
incompatibility with human rights. Fourthly,
while Parliament may be prompted to reconsider
legislation in light of court judgments,
Parliament always has the ‘final say’ about
laws.16 Finally, legislative dialogue instruments
are ordinary Acts of Parliament. They are
not entrenched in the Constitution and may
be amended or repealed by Parliament. Any
institutional power that flows to the judiciary is
granted by Parliament itself and can be adjusted
by Parliament.
Other domestic human rights instruments draw
a different balance between the powers of the
legislature and the judiciary. For example, in the
USA and South Africa, rights are entrenched
in the Constitution, and courts have greater
institutional power to enforce human rights. If
the legislature passes laws that are inconsistent
with human rights, courts are empowered to
invalidate the legislation.
The distribution of responsibility between the
judiciary and the Parliament in the dialogue
model recognises the dual role each branch has
in fulfilling democratic principles. The courts
are essential to maintaining the rule of law
and protecting individuals against injustice –
both fundamental democratic requirements.
Legislation is usually drafted in a manner that
is intended to be generally applicable to the
broader population. Sometimes individuals or
groups whose interests are not represented
by majority concerns, slip through the cracks
in these laws.17 Providing the courts with the
ability to consider human rights in relation
to individuals, while maintaining the intent of
Parliament, helps to ensure that legislation
applies fairly and inclusively to all, even those
who may be low on the list of parliamentary
priorities. In this regard, former UK Supreme
Court Justice, Lady Hale, succinctly explained
that ‘democracy values everyone equally, even
if the majority does not’.18
In the pivotal case under the Human Rights Act
1998 (UK) (UK Human Rights Act), Belmarsh,
Lord Bingham elaborated on the broader role
of the judiciary in a democracy, in light of its
functions under the UK Human Rights Act:
It is of course true that the judges in
this country are not elected and are
not answerable to Parliament. It is also
of course true … that Parliament, the
executive and the courts have different
functions. But the function of independent
judges charged to interpret and apply the
law is universally recognised as a cardinal
feature of the modern democratic state,
a cornerstone of the rule of law itself.19
Lord Bingham’s comment highlights that the
court’s role under a Human Rights Act does not
stand in opposition to democratic government,
rather it is fundamental to its functioning to the
fullest of democratic ideals. All three branches
of government support a common cause – and
the dialogue model recognises this intersection,
encouraging the development of shared norms.
