Evaluate the following scenarios to determine which are recognized by the Supreme Court (Bommai case, 1994) as constitutionally 'proper' justifications for the invocation of Article 356 (President's Rule):
1. A scenario where a state administration explicitly disregards and fails to comply with a constitutional directive issued by the Union government.
2. A scenario characterized by severe bureaucratic maladministration and widespread, unproven allegations of corruption against state ministers.
3. A scenario following a general election where the legislative assembly is hopelessly 'hung' and no coalition can secure a functional majority.
4. A scenario where the ruling state apparatus is deliberately engaging in internal subversion against the national Constitution.
