Exercising discipline, in the punishment sense, can be one of the trickiest tasks for any party leader, especially a prime minister.
It would perhaps help if each prime minister left the next one a set of "sentencing guidelines" because relativity is important, if not between governments, certainly within them.
The test is: "Is it fair?" And the test needs to be satisfied for the voter and for the party.
In the case of Clare Curran, she has been demoted from inside cabinet to outside cabinet and lost two of her four portfolios including open government.
