The Immigration Department appealed the ruling to the Court of Final Appeal. The court handed down its ruling on 4 July 2018, finding in favour of the plaintiff and mandating immigration authorities to grant same-sex partners spousal visas that were previously only available only to heterosexual couples. The panel of judges, led by Chief Justice Geoffrey Ma Tao-li, held that the “policy [of not granting a visa] is counterproductive and plainly not rationally connected to advancing [any] ‘talent’ aim" and rejected the immigration director’s argument that civil union partnerships differed from marriage, saying it was based on a “shaky foundation [and]...hardly satisfactory”. The government stated it respected the court's ruling and would study it in detail.
Homosexuality is immoral and unnatural. J. Matt Barber, Associate Dean for Online Programs at Liberty University School of Law, stated that "Every individual engaged in the homosexual lifestyle, who has adopted a homosexual identity, they know, intuitively, that what they're doing is immoral, unnatural, and self-destructive, yet they thirst for that affirmation." A 2003 set of guidelines signed by Pope John Paul II stated: "There are absolutely no grounds for considering homosexual unions to be in any way similar or even remotely analogous to God's plan for marriage and family... Marriage is holy, while homosexual acts go against the natural moral law."  Former Arkansas governor and Republican presidential candidate Mike Huckabee stated in Oct. 2014 that gay marriage is "inconsistent with nature and nature’s law." 
In some cases bisexuality is actually a form of fitness favored by evolution. For example, in the absence of male whiptail lizards (Cnemidophorus), females reproduce by pairing up with each other. During the breeding season females will take turns switching between "male" and "female" roles as their hormones fluctuate. Estrogen levels are high during ovulation ("female" role) and much lower after laying eggs ("male" role). While in the "male" role, a female lizard will mount another in the "female" role and go through the motions of sex to stimulate egg-laying. The hatchlings produced are all female. This all-female species has evolved from lizards with two sexes, but their eggs develop without fertilization (parthenogenesis). Female whiptail lizards can lay eggs without sex, but they lay far fewer eggs than if they engage in sexual stimulation by another female.
The NAACP, the leading African-American civil rights organization, has pledged its support for gay rights and same-sex marriage, stating that they "support marriage equality consistent with equal protection under the law provided under the Fourteenth Amendment of the United States Constitution", and has declared that same-sex marriage is a civil right.
In 1995 MCC, ProGay Philippines and other organizations held internal celebrations. In 1996, 1997 and 1998 large and significant marches were organized and produced by Reachout AIDS Foundation, all of which were held in Malate, Manila, Philippines. In 1998, the year of the centennial commemoration of the Republic of the Philippines, a Gay and Lesbian Pride March was incorporated in the mammoth "citizens' parade" which was part of the official centennial celebration. That parade culminated in "marching by" the President of the Philippines, His Excellency Joseph Estrada, at the Quirino Grandstand in Luneta Park in Manila.

On 10 April 2013, the Chamber of Deputies passed the amended bill by a two-thirds majority (71–22). The president promulgated the law on 3 May 2013 and it took effect on 5 August.

Male bisexuality is particularly presumed to be non-existent, with sexual fluidity studies adding to the debate. In 2005, researchers Gerulf Rieger, Meredith L. Chivers, and J. Michael Bailey used penile plethysmography to measure the arousal of self-identified bisexual men to pornography involving only men and pornography involving only women. Participants were recruited via advertisements in gay-oriented magazines and an alternative paper. They found that the self-identified bisexual men in their sample had genital arousal patterns similar to either homosexual or heterosexual men. The authors concluded that "in terms of behavior and identity, bisexual men clearly exist", but that male bisexuality had not been shown to exist with respect to arousal or attraction. The assertion of Bailey that "for men arousal is orientation" was criticized by Fairness and Accuracy in Reporting (FAIR) as a simplification which neglects to account for behavior and self-identification. Further, some researchers hold that the technique used in the study to measure genital arousal is too crude to capture the richness (erotic sensations, affection, admiration) that constitutes sexual attraction. The National Gay and Lesbian Task Force called the study and The New York Times coverage of it flawed and biphobic.
There is no complete data on the number of same-sex marriages conducted in the United States. Marriages and divorces are recorded by states, counties, and territories, plus New York City and the District of Columbia, but not by the federal government. States such as Oregon do not distinguish between opposite-sex and same-sex marriages in their official records. The legal records on marriage and divorce belong to the states. In August 2016, the Treasury Department estimated the number of same-sex marriages by linking the tax returns of same-sex couples who had filed jointly in 2014 with their Social Security records. (Although this method excluded couples who file singly, these are small in number; of all married couples who file taxes, 97.5% file jointly.) This research showed that in 2014 there were about 183,280 married same-sex couples in the country, or "roughly a third of 1 percent of all marriages" according to the New York Times.
Another parade, this time billed as an international event, was scheduled to take place in the summer of 2005, but was postponed to 2006 due to the stress on police forces during in the summer of Israel's unilateral disengagement plan. In 2006, it was again postponed due to the Israel-Hezbollah war. It was scheduled to take place in Jerusalem on November 10, 2006, and caused a wave of protests by Haredi Jews around central Israel. The Israel National Police had filed a petition to cancel the parade due to foreseen strong opposition. Later, an agreement was reached to convert the parade into an assembly inside the Hebrew University stadium in Jerusalem. June 21, 2007, the Jerusalem Open House organization succeeded in staging a parade in central Jerusalem after police allocated thousands of personnel to secure the general area. The rally planned afterwards was cancelled due to an unrelated national fire brigade strike which prevented proper permits from being issued. The parade was postponed once more in 2014, as a result of Protective Edge Operation.
