Abolition of death penalty. 4. A person is not liable to the punishment of death for any offence.
Substitution of imprisonment for life. 5. Where by any law in relation to which this Act applies (including a provision that would, but for this Act, have effect by virtue of such a law) it is provided that a person is liable to the punishment of death, the reference to the punishment of death shall be read, construed and applied as if the penalty of imprisonment for life were substituted for that punishment.
