British citizens must earn more than 18,600 pounds a year before a husband or wife from outside the European Economic Area (EEA), including countries like India, can settle in the UK. The rule had been introduced in 2012 to stop foreign spouses becoming reliant on UK taxpayers.
The minimum income threshold, which also affects people settled in the UK as refugees, rises to 22,400 pounds if the couple have a child who does not have British citizenship and then by an additional 2,400 pounds for each subsequent child.
They, however, did acknowledge that the rules did cause "hardship" to a lot of families and concluded that the "rules and instructions" require amendment in relation to the duty towards children and other funding sources available to the couple.
While the exact numbers affected remains unclear, some Indians are likely to be among the nationalities affected by the 18,600-pound a year earning criteria for a British national to sponsor his or her foreign spouse to live in Britain.

Abdul Majid and Shabana Javed were joined by a Lebanese refugee who cannot find suitable work in the UK despite his post-graduate qualifications and could not bring his wife and a refugee from the Democratic Republic of Congo, whose wife has been barred from settling in the UK.
A UK Home Office spokesperson said: "The court has endorsed our approach in setting an income threshold for family migration that prevents burdens on the taxpayer and ensures migrant families can integrate into our communities.
The policy had been brought in by British Prime Minister Theresa May during her term as Home Secretary under the David Cameron led government.
A report released in 2015 had warned that the threshold was creating "Skype families" and separating loved ones.
"The threshold is too high and is discriminatory. British citizens who have lived and worked abroad and formed long-term relationships abroad are particularly penalised and find it very difficult to return to the UK," the report titled 'Family Friendly?' had said.
