[6] Of his legacy as mayor, the salvation of the spa resort Caldea, the protection of the Madriu Valley and the consolidation of the Clot d'Emprivat area stand out.

[9] After days of negotiation and uncertainty, on 17 February 2011 Martí announced that he was standing as the candidate for the centrist coalition (Democrats for Andorra) on the national list for the 2011 early elections.

[12][13] On 3 April 2011, Democrats for Andorra (DA) won an overwhelming absolute majority, achieving the 55.15% of the vote and winning 21 seats in the General Council.

[14] The General Council session to inaugurate Martí as prime minister took place on 11 May 2011, and he announced that his main objectives for his mandate were economic recovery, the promotion of tourism and the country's rapprochement with the European Union while offering state agreements with the opposition on issues such as the Andorra-EU relationship, social security and local administration.

[15][16] The first five measures that the Martí government approved were: the flexibilisation of business hours, the revision of the land law, the revision of the law on income tax for non-resident taxpayers, the reduction of contributions for the self-employed and the urgent processing of several commitments that Andorra must take for the evaluation of the Council of Europe's Committee of Experts on the Evaluation of Anti-Money Laundering Measures and the Financing of Terrorism.

[30] The board of directors and three of the bank's managers were suspended as of 11 March 2015 by the Institut Nacional Andorrà de Finances under orders of the Andorran government.

[31] Martí, while being acting prime minister, reported that the US authorities had informed him days before and that it was a case of "bad practices and not a situation of solvency risk or balance sheet problems", calling on the citizens to remain calm, as the government had appointed two auditors to "guarantee the continuity of the institution's normal operations, protect its customers and ensure the good name and integration of the Andorran financial centre".

[37] Following the terrorist attacks in Barcelona and Cambrils on 17 August 2017, Martí offered a grand bargain to the opposition to provide the Police Corps with more troops and create a specific counter-terrorism unit.

[40] When the President of the Generalitat de Catalunya Carles Puigdemont declared Catalonia's independence from Spain, only to suspend it shortly afterwards, on 10 October 2017, Martí acknowledged that, although he stated that he had never proposed himself as mediator to the Spanish Prime Minister Mariano Rajoy, he did have telephone contacts with both parties to discuss the constitutional crisis.

[42][43] In his last address to the General Council as prime minister, Martí stated that decriminalising abortion was incompatible with maintaining the country's political system.

[54] The state funeral took place on 8 November in the parish church of Saint Peter Martyr in Escaldes-Engordany and was presided by the episcopal co-Prince Joan Enric Vives i Sicília.
