What is the difference between "appropriate proceedings" and "all or any of the powers exercisable by the Supreme Court under clause (2)" in Article 32(3)?
There is no difference between "appropriate proceedings" and "all or any of the powers exercisable by the Supreme Court under clause (2)" in Article 32(3) because both phrases refer to the legal actions taken for enforcing the rights conferred by Part III of the Indian Constitution. The right guaranteed by Article 32 is the power to move the Supreme Court or other courts with jurisdiction, as granted by Parliament, using various legal mechanisms such as writs in the nature of habeas corpus, mandamus, prohibition, quo warranto and certiorari, depending on the circumstances. The use of "appropriate proceedings" is a general term that can encompass any or all of these powers under clause (2).
