In January 2020, Bob Brown, a Minister of the Federal Executive arm of government, holds a meeting with Justices Apple, Bruce and Carmel of the Court of Appeal in Western Australia. In the meeting, Bob Brown expresses his disapproval of Justices Apple and Bruce's recent decision in which the Court reduced the sentence of a convicted drug trafficker from 20 years to 10 years.

On the other hand, Bob Brown praised Justice Carmel, who disagreed with the majority decision. Bob Brown makes it clear to Justices Apple and Bruce that if they continued to reduce sentences for drug-related offences, Bob Brown would immediately remove them from office and temporarily appoint Smith and Princeton to replace them. Smith is a member of the upper house in the Western Australia State government. Princeton is another member of the Federal Executive arm of government. Both have publicly expressed concern regarding lenient judicial sentences.

With reference to any fundamental principles of government in Australia, for instance the separation of powers, discuss any issues with the above interactions.
