Today marks a victory not for myself or for the UNP. It is a victory for Sri Lanka’s democratic institutions and the sovereignty of our citizens. I thank everyone who stood firm in defending the constitution and ensuring the triumph of democracy.

Incumbent president Maithripala Sirisena , who had precipitated the constitutional crisis  in Sri Lanka by removing  Wickremesinghe as prime minister on October 26 and appointing the former president and opposition Member of Parliament Mahinda Rajapaksa  to replace him, defended his actions, saying:

President Sirisena suspended  the country’s parliament for three weeks and dissolved  the cabinet of ministers. Wickremesinghe protested  his removal, claiming it was unconstitutional, with many supporters  rallying behind him and demanding the reconvening of the parliament for a floor test . See Groundviews’ timeline  of the constitutional crisis.
Sri Lankan citizens protested almost every day  since the start of the crisis, taking a stand for democracy.

President Maithripala Sirisena responded to the pressure and reconvened parliament on November 14, but rejected two no-confidence  motions against Rajapaksa. Ranil Wickremasinghe and 121 other parliamentarians then went to court  seeking a writ of quo warranto , which would require Rajapaksa to show what authority empowers him to exercise the office of prime minister. On December 3, a Sri Lankan Appeals Court issued  an interim injunction restraining Rajapaksa from the office  of prime minister until the petition challenging his appointment was heard.

A blog post on Groundviews quoted attorney-at-law Dinesha Samaratne , who said that the Supreme Court decision should be welcomed and celebrated:
The Parliament stands and its declaration of no-confidence in MP Rajapakse (through two separate motions) and its declaration of confidence in Prime Minister Wickremesinghe clarifies that Ranil Wickremesinghe continues to enjoy the confidence of a majority in Parliament. The only way forward is for the President to rescind his purported appointment of MP Rajapakse as Prime Minister and his purported appointment of a Cabinet of Ministers. The status quo prior to 26th October has to be restored.
The Groundviews story also quoted attorney-at-law Luwie Ganeshathasan, who said that:
The decision re-affirmed that Sri Lankan citizens had a right to be governed according to the Constitution as well as a right to participate in elections according to established procedures of the law, as opposed to on the whim of one individual.
Ashraf Hegazy and Gary Milante noted in Groundviews  that the political crisis went largely remained unnoticed in the international press, but that:
How Sri Lankans have responded to these events demonstrates the resilience that they have built into their systems of government and social norms.
On December 16, netizen recalled on President Sirisena's November statement  that he would resign immediately if Wickremesinghe came back.
Really, can someone ask @MaithripalaS  / @PMDNewsGov  why after more than one hour after swearing in Wickremesinghe, he is still President & hasn't resigned? #couplk  #lka  #srilanka

I am too excited for tomorrow! No! Not because Mr. Ranil Wickramasinghe is Prime minister again. Just to see Mr. Maithreepala Sirisena’ s face turns red when he meet UNP MPs. — feeling blah

According to media reports , a new cabinet will be sworn in on December 17, 2018, and will include six parliamentarians from Rajapaksa and Sirisena's factions of the Sri Lanka Freedom Party (SLFP). Wickremesinghe's United National Party (UNP) has said  that it is ready to work once more with President Maithripala Sirisena, who was “misled by some groups” against the unity government. In August 2015, Sirisena and Rajapaksa’s Sri Lanka Freedom Party (SLFP) and Wickremesinghe-led United National Party (UNP) created a national government after signing an agreement .
Where do we stand right now? Well, the President cannot dissolve Parliament arbitrarily. Parliament itself is at a standstill thanks to the antics of the Parliamentarians, a clearly partisan Speaker, a stubborn President and a court order. We will have to wait and see if the key players in the drama can rise above their personal and political agenda to resolve things.
It remains unclear that how this political crisis and the differences between Sirisena and Wickremesinghe will play out  in this “new government”.
