# Incumbent Benchmark — Event Dossier # Category: entrenchment / executive self-aggrandizement checked by courts and legislature id: sri-lanka-2018-crisis title: "Sri Lanka 2018: The 52-Day Constitutional Crisis (Two Prime Ministers)" category: entrenchment country: "Sri Lanka" year: 2018 date_range: "2018-10-26 to 2018-12-16" summary: > On 26 October 2018, President Maithripala Sirisena withdrew his party from the governing coalition, declared Prime Minister Ranil Wickremesinghe dismissed, and swore in Mahinda Rajapaksa — the former president he had defeated in 2015 — as prime minister within hours. Wickremesinghe refused to vacate, correctly noting that the 19th Amendment (2015) had removed the president's power to dismiss a prime minister who retained parliamentary confidence. Sirisena prorogued parliament to delay a floor test while defections were courted, and when the numbers failed to materialize, dissolved parliament on 9 November and called snap elections — despite the 19th Amendment's explicit bar on dissolution before four and a half years absent a two-thirds parliamentary request. The Supreme Court stayed the dissolution within four days, parliament passed no-confidence motions against Rajapaksa amid physical brawls in the chamber, the Court of Appeal restrained the purported cabinet from functioning, and on 13 December a seven-judge Supreme Court bench unanimously held the dissolution unconstitutional. Rajapaksa resigned on 15 December; Wickremesinghe was reinstated on 16 December. The incumbent system, unusually in this benchmark, repelled the capture attempt through lawful institutions in 52 days — though one bystander was killed, governance froze for two months, and the underlying presidential-parliamentary tension resurfaced in later crises. incumbent_constitution: name: "Constitution of Sri Lanka (1978) as amended by the 19th Amendment (2015)" relevant_provisions: - ref: "Art. 42(4)" text_gist: "The President appoints as Prime Minister the MP who in the President's opinion is most likely to command the confidence of Parliament." - ref: "Arts. 46(2), 48" text_gist: "Post-19th Amendment, the PM ceases to hold office only by resignation, ceasing to be an MP, or the government losing confidence — the pre-2015 dismissal-at-will power was removed." - ref: "Art. 70(1) (as amended)" text_gist: "The President may not dissolve Parliament until four and a half years of its term have elapsed, unless Parliament requests dissolution by a two-thirds resolution." - ref: "Art. 33(2)(c)" text_gist: "General presidential powers including summoning, proroguing, and dissolving Parliament 'subject to the provisions of the Constitution' — the clause Sirisena read as a freestanding dissolution power." - ref: "Art. 126" text_gist: "Fundamental-rights jurisdiction of the Supreme Court — the vehicle for the dissolution challenge." structural_defects: - "Textual seam between Art. 33(2)(c)'s general power and Art. 70's specific bar invited a bad-faith reading;

Costs were economic and reputational. The Art. 33/70 seam was authoritatively closed by the ruling. However, the 20th Amendment (2020) under the next government reversed much of the 19th, showing the settlement did not entrench." trust_impact: "Mixed-positive: the Supreme Court and the Speaker emerged strengthened; the presidency damaged.

Eliminates the three-week blockade that was the whole strategy." - mechanism: purpose_constraint_on_procedural_powers relevance: "Kernel procedural powers (scheduling, prorogation analogues) carry a justiciable purpose constraint — the same principle the UK Supreme Court would articulate in Miller II ten months later, and which Sri Lanka's courts reached via Art. 70." - mechanism: anti_entrenchment_invariant relevance: "A dissolution that resets the body empowered to check the dissolver is a power-allocation change and must pass the gate (here: the two-thirds parliamentary request route, which is the incumbent's own version of the rule — the kernel makes it the only route, removing the Art. 33 seam)." - mechanism: vote_integrity relevance: "Recorded, name-call voting with cryptographic attestation is the kernel default; the disputed voice votes of 14 November would have been undisputable." - mechanism: independent_adjudication relevance: "The incumbent's courts performed close to the kernel's specification: fast interim relief, unanimous final ruling, universal compliance. This dossier is a calibration point — the kernel should not dramatically outperform here, and a benchmark that says otherwise is overclaiming." expected_intervention_points: - "26 October: rival PM appointment triggers the mandatory floor test clock; prorogation during the pending test is void." - "9 November: dissolution outside the supermajority-request route is void on issuance rather than after 34 days of litigation." - "Defection window: kernel's recorded-vote and public-ledger rules raise the cost of vote-buying without banning genuine realignment." simulation: seed: 2018 rounds: 10 capture_agents: - actor: sirisena objective: install-minority-government tactics: ["irregular dismissal", "prorogation to block floor test", "prohibited dissolution", "defection inducement"] stress_parameters: legitimacy_split: 0.45 security_forces_alignment: neutral adjudicator_enforcement_power: high legislature_cohesion: "majority holds under inducement pressure" economic_pressure: medium pass_conditions: - "Floor test occurs within the kernel's fixed window in every branch; no game path allows an untested government to operate ministries." - "Dissolution move outside the supermajority route is void with standing cost; capture agent's expected value from attempting the sequence is negative." - "Worst-off participant (citizen agent class) experiences no rights suspension and bounded service disruption (< 1 round of contested administration)." - "Calibration check: kernel margin over incumbent on this event must be small and positive, not large — the incumbent substantially succeeded here." sources: - "Constitution of Sri Lanka, Arts. 33, 42, 46, 48, 70 (as amended by the Nineteenth Amendment, 2015)." - "Supreme Court of Sri Lanka, SC FR 351/2018 and connected petitions, judgment of 13 December 2018." - "Court of Appeal, CA Writ 363/2018 (quo warranto), interim order of 3 December 2018." - "Hansard, Parliament of Sri Lanka, sittings of 14–16 November 2018." - "Centre for Policy Alternatives (Colombo), litigation papers and crisis analyses, October–December 2018." - "International Crisis Group and contemporaneous reporting on the CPC shooting and defection allegations."
