5. Multi-Dimensional Analysis

Legal/Constitutional — floor test is confidence-motion mechanism to prove majority under Art. 164/collective responsibility (Art. 164(2)); rebel MLAs voting against party line raises anti-defection (Tenth Schedule) disqualification questions, esp. if whip issued [1]. Governance/Ethical — party-internal expulsion vs Assembly voting rights: Palaniswami's sacking of rebels post-vote signals accountability battle within AIADMK, not disqualification from House [1]. Historical — TN politics precedent of splits (1972 DMK-AIADMK split, 2017 AIADMK-TTV Dhinakaran split) — recurring pattern of Dravidian-party fragmentation now involving TVK entrant [1]. Administrative — coalition arithmetic: TVK anchored, backed by Congress, Left parties, VCK, IUML, plus defector MLAs — signals fragile multi-party coalition management going forward [2].

10. Common Errors / Trap Areas

• Confusing "sacking from party post" with "disqualification from Assembly" — these are legally distinct (party discipline vs Tenth Schedule) [1].
• Assuming floor test requires Governor's direct involvement each time — actually Speaker conducts the vote in House [1].
• Mixing up AIADMK factions: Palaniswami camp vs Velumani-rebel camp vs AMMK (Dhinakaran) — three distinct entities [1].
• Treating "abstention" as vote in favour — abstaining MLAs (PMK, BJP) are neither for nor against; don't add to majority count carelessly [1].
• Assuming TVK is renamed AIADMK/DMK faction — it's a distinct new party led by Vijay [1].
