Pre-poll coalitions in India often lack durability. Analyse the reasons and their implications for federal democracy.

Pre-poll coalitions are alliances agreed before an election, usually through seat-sharing. The Sarkaria Commission ranked them first when a Governor invites a party to form a government [2]. Yet many break apart because they are built on electoral arithmetic, not shared ideology.

Reasons for low durability

• Arithmetic over ideology: Many alliances are formed mainly to defeat a common rival, with no binding common programme. AAP's exit from the INDIA bloc shows this fragility [1].
• Clashing state-level interests: Parties that are allies nationally are often direct rivals in the states. This makes seat-sharing a zero-sum contest.
• Leadership and organisational gaps: There is often no agreed leader and no joint machinery. The BJP blamed the INDIA bloc's postponed mock Parliament on a "lack of organisational capability" [1].
• Legal vacuum: The Tenth Schedule binds individual legislators to their party, but it does not bind parties to an alliance [3]. A whole party can therefore walk out without penalty. Examples are the Shiv Sena leaving the BJP after the 2019 Maharashtra polls and the JD(U) quitting the Mahagathbandhan in 2017.
• Post-poll bargaining: Hung verdicts reward switching sides for ministerial posts.

Implications for federal democracy

Positive

• Regional voice at the Centre: Coalitions bring state concerns into national policy, which strengthens cooperative federalism.
• Checks on central overreach: In S.R. Bommai (1994), the Supreme Court held that a majority must be tested on the floor of the House [4]. This narrowed the room for misusing Article 356 when coalitions break.

Negative

• Betrayed mandate: Voters who backed a joint platform see it dissolved after the election. This weakens electoral trust.
• Instability and friction: Frequent changes of government stall policy. They also turn the Governor's discretion and floor tests into Centre–State flashpoints.
• Weak opposition: A divided opposition weakens accountability in Parliament and pushes dissent outside it, as with mock Parliaments [1].

The weak points of these coalitions (opportunism, rival state interests and the legal vacuum) also explain most of their cost to federalism, even though they give the states more voice. The way forward is a written common minimum programme, standing coordination committees and legal recognition of pre-poll alliances as a single unit, as the Punchhi Commission suggested. Together these can turn alliances of convenience into stable partnerships that serve the constitutional ideal of cooperative federalism.
