Mass protests and campaigns In September 2011 Yavlinsky was appointed head of the electoral list of Yabloko Party for the
State Duma elections of the sixth convocation by a resolution of the party's congress. According to the official results of the elections held on 4 December 2011, Yabloko failed to surmount the five per cent barrier and as a result was not accorded any seats in the Russian parliament. However, the party gained more votes than in previous elections (3.43%), thereby securing state financing. At the same time, Yabloko candidates were elected in three regions, including the Legislative Assembly of Saint Petersburg where the party won 12.5% of the votes and six mandates. Yavlinsky, who also headed the party list for these elections, agreed to head the Yabloko fraction in Saint Petersburg and received the mandate of a state deputy on 14 December 2011. On 18 December 2011 Yavlinsky was nominated by the Yabloko Party congress as the party's candidate for
the Russian presidential elections scheduled for 4 March 2012. On 18 January 2011 he submitted to the
Central Electoral Commission of the Russian Federation the 2 million signatures in support of his candidacy required to participate in the elections. After checking the signatures, the commission claimed to have identified photocopies of signatures and refused to register Yavlinsky as a candidate, rejecting 25.66% of the submitted signatures on the grounds that they were defective. On 8 February 2012 the
Supreme Court of the Russian Federation rejected Yavlinsky's appeal against the decision of the Central Electoral Commission, finding the decision not to register his candidacy to be legal. Commenting on his disqualification, Yavlinsky declared that the decision was politically motivated. Yavlinsky actively supported the
protests in Russia in December 2011 – March 2012 against the falsifications during the elections and was a frequent speaker at the meetings "For Fair Elections" in Moscow. On 14 and 15 May he visited Saint Isaac's Square in Saint Petersburg where the opposition camp was located. He participated in the "March of Millions" in Moscow on 6 May and 12 June.
Legislation At the elections of deputies of the
Legislative Assembly of Saint Petersburg of the 5th convocation Yavlinsky was the only candidate in the municipal part of Yabloko's list and on this basis headed the party at the Saint Petersburg elections. According to official data, the party won 12.5% of the votes and formed a faction of six deputies in the city parliament. It was submitted in February 2015 to the Governor of the city
Georgy Poltavchenko. In April 2015 Yavlinsky outlined the key concepts of the document to representatives of the authorities and business of Saint Petersburg and Leningrad Region at the first strategic session held as part of preparations for the forum "Harmony of Versatility". During the five years of work of the Yabloko fraction headed by Yavlinsky, Saint Petersburg's parliament adopted 25 per cent of the numerous initiatives proposed by Yabloko's deputies (almost 100 in total).
Opposition to the Russo-Ukrainian War At the end of February 2014 Yavlinsky published in the Russian business daily
Vedomosti an article with the heading "Russia is creating a zone of instability around its borders". He wrote that a social contract had existed in Ukraine until the end of autumn 2013: the people had been prepared to endure
Yanukovych as long as they could see the country moving towards Europe. Yavlinsky notes in the article that on the eve of the signing of the
EU Association Agreement, it became clear that the European option was not splitting the country: on the contrary, it was bringing people together. Notwithstanding all the serious Ukrainian internal drivers of the evolving crisis, it was primarily attributable to developments in Russia:Russia's unnatural refusal to move along the European path implies a rift in the post-Soviet space. The Ukrainian crisis is the result of this rift. Instead of moving together with Ukraine towards Europe, Russia is trying to draw the country in the diametrically opposing direction. Through its renunciation of the European vector, Russia is creating a zone of instability, as virtually all its Western and even southern neighbours are in the final analysis striving for Europe. Accordingly, all these countries will have significant forces fighting Russia's plans to hold them back and not let them go. Sooner or later the instability caused by this erroneous anti-European course will also come to Russia itself. In the article, he wrote in particular:The positions and actions of the powers-that-be in Russia in respect of Ukraine and in connection with developments there are a reckless political adventure. We believe that it is absolutely unacceptable to even raise the idea of using Russian troops in Ukraine. This is the position held by Yabloko. We also believe that the separation of Crimea from Ukraine and its annexation is an error at the national level. The fundamental goal of such a policy implemented by the leadership of our country is clear. This is the positioning of Ukraine as a "failed state", which is popular among the entourage close to the powers that be. They tend to believe that it is in Russia's interests to push Ukraine into political degradation and territorial collapse, or to transform it into a puppet state. We are convinced that it is in Russia's interests to make an immediate break with such ideology and to bring such policies to an end. The immediate result of Crimea's annexation would be to transform Russia into a country with zero reputation and borders that are not recognised internationally.On 13 December 2014 at a Yabloko Party meeting, Grigory Yavlinsky advocated the creation of a "buffer zone" between Russia and Ukraine, with the participation of international observers, negotiations with Ukraine's leadership, the removal of mercenaries and materiel from the country and the provision of guarantees to the public which should in the end lead to the holding of a "legitimate referendum" on the status of Crimea organised under Ukrainian law "so that this problem does not haunt Russia forever". "We need to say: Yes, Crimea is not our territory". At the same time, Yavlinsky stated that Crimea's future should be determined by the inhabitants of the peninsula on the basis of respective legislation: "We hold that the referendum on 16 March 2014 was illegal, conducted in a rush with utter disregard for any rules, laws and norms and under the "protection" of the Russian Armed Forces." "I want my country to have internationally recognised borders. I want people living in Crimea to be fully-fledged citizens of Europe. However, the key is that this issue should be resolved in such a way that Russia can say: We are a European country, we are building our future together with Europe on the same rules governing how hundreds of millions of people live". The politician proposed that a "legal and legitimate referendum (or local referenda with prospects of the cantonisation of Crimea)" be held based on Ukrainian legislation and international norms of law "agreed with Kyiv, the Crimean authorities, Russia, the
EU,
OBSE and
the United Nations." Such a referendum conducted under stringent international control should contain three questions: whether the people want to live as part of Ukraine, as an independent Crimean state or as part of Russia. In 2017 Yavlinsky developed a peace plan for Donbas consisting of 10 points. The plan provided guarantees for the long-term safety of the region's inhabitants and proposed an end to the war. It was one of the key policy documents of Yavlinsky's presidential campaign in 2018. == 2016 parliamentary elections ==
