Evaluate the functional discrepancies between Article 358 and Article 359 regarding the curtailment of civil liberties during a proclaimed National Emergency:
1. Under the provisions of Article 359, the fundamental liberties guaranteed by Articles 20 and 21 suffer compulsory and immediate suspension.
2. Unlike the discretionary nature of Article 359, Article 358 triggers an automatic suspension of specific fundamental freedoms immediately upon proclamation.
3. Unlike the universal application of Article 359, the operational scope of Article 358 is strictly confined exclusively to External Emergencies.
