In what ways could the executive arm of government interfere with the independence of the judiciary?

• POLITICAL APPOINTMENT: The appointment of judges is influenced by the
  executive. The executive have often used
  their power to appoint those who
  will support their policies. 
• DISRESPECT FOR COURT DICISION OR ORDERS:- Sometimes decisions of law courts are not
  obeyed by the executive. 
• INADEQUATE
  FUNDING: Sufficient funds are not allocated to the
  judiciary in the annual budget usually prepared” by the executive. 
• SETTING
  UP OF TRIBUNALS: Sometimes, people making up the tribunals do
  not have .proper legal training hence cannot interpret laws
  adequately. 
• REMOVAL OF JUDGES: Sometimes, the executive removes judges from
  office for not favouring them. 
• BACKDATING OF LAWS: In Britain, for instance, no court can
  question the Acts of Parliament because of its
  supremacy. The parliament can even
  backdate laws to favour a particular interest regardless of 
  court’s decision. 
• PROMOTION
  OF JUDGES: Promotion of judges to the high rank is
  done by the executive. .i.e. Judges moving from high court to federal appeal
  court or appeal court to supreme court. 
• POLITICAL INTERFERENCE: Often times, the decisions of the court may
  unduly >be influenced by the executive. 
• DECREES: Miliiary regimes made decrees or laws that
  cannot be challenged in any court.
