Exclusive cognisance refers not simply to Parliament, but to the exclusive right of each House to manage its own affairs without interference from the other or from outside Parliament. The boundaries of exclusive cognisance result from accord between the two Houses and the courts as to what falls within the exclusive province of the former.
