However, the proposed change was dropped from the draft constitution in December 2018. Before the October 2017 election, LGBT activists started a public campaign with the aim of achieving same-sex marriage within the next four years. Prime Minister Andrej Babiš supports the legalisation of same-sex marriage. A bill to legalise same-sex marriage was introduced to the Czech Parliament in June 2018. Recent opinion polls have shown that the bill is quite popular in the Czech Republic; a 2018 poll found that 75% of Czechs favoured legalising same-sex marriage. In August 2016, a lawyer in El Salvador filed a lawsuit before the country's Supreme Court asking for the nullification of Article 11 of the Family Code, which defines marriage as a heterosexual union. Labeling the law as discriminatory and explaining the lack of gendered terms used in Article 34 of the Constitution's summary of marriage, the lawsuit sought to allow same-sex couples the right to wed. On 20 December, the Salvadoran Supreme Court rejected the lawsuit on a legal technicality. A second lawsuit against the same-sex marriage ban was filed on 11 November 2016. On 17 January 2019, the Supreme Court dismissed the case on procedural grounds. The 2018 Inter-American Court of Human Rights ruling regarding the legalisation of same-sex marriage in countries that have ratified the American Convention on Human Rights applies to El Salvador. In October 2014, the Estonian legislature, the Riigikogu, approved a civil union law open to both opposite-sex and same-sex couples. In December 2016, the Tallinn Circuit Court ruled that same-sex marriages concluded in another country must be recorded in the civil registry. However, they do not count as marriages for the purpose of granting spousal residency rights. In 2016, a man filed a challenge against Georgia's same-sex marriage ban, arguing that while the Civil Code of Georgia states that marriage is explicitly between a man and a woman; the Constitution does not reference gender in its section on marriage. In September 2017, the Georgian Parliament approved a constitutional amendment establishing marriage as "a union between a woman and a man for the purpose of creating a family". President Giorgi Margvelashvili vetoed the constitutional amendment on 9 October. Parliament overrode his veto on 13 October. Same-sex marriage is not explicitly prohibited under Indian law and at least one couple has had their marriage recognised by the courts. In April 2014, Medha Patkar of the Aam Aadmi Party stated that her party supports the legalisation of same-sex marriage.
