Operation Dharmic Vote, launched a few years ago, has highlighted a short-list of candidates that support their so- called "dharmic duties" by opposing the introduction of such a legislation which they claim will cause conflict within Britain's Hindu community.
The UK government had launched a consultation on the issue earlier this year following a nationwide campaign in favour of such a legislation by Dalit bodies in the country.
"If re-elected, I would seek the support of the government and fellow MPs to repeal both the caste clause in the legislation and the parliament to overturn any adverse judgments in case law," says Bob Blackman, seeking re-election as Conservative MP for Harrow East - an area of north-west London with a large proportion of British Hindus.
The Liberal Democrat party, which has fielded 14 Indian- origin candidates in this election, has made it a manifesto pledge to support the introduction of caste legislation while other parties are more wary of the issue.

Sunder Katwala, director of independent thinktank British Future, believes that British-Indian voters in this general election will ultimately vote based on wider national issues of concern such as Brexit.
He explained: "British-Asian voters mostly share the same concerns as their white neighbours in this election: the economy, the National Health Service, the party leaders and Brexit.
"While Theresa May's pitch to deliver Brexit will appeal to the third of Asian voters who voted to leave the European Union, and to many Remainers who now want the UK to implement the referendum decision, she must strike a balance.
The Conservatives this time have fielded 13 Indian-origin candidates including incumbent MPs Priti Patel, Alok Sharma, Shailesh Vara, Rishi Sunak and Suella Fernandes and hopefuls Rahoul Bhansali, Samir Jassal, Ameet Jogia, Resham Kotecha, Reena Ranger, Meera Sonecha, Minesh Talati and Paul Uppal.
Among the unelected Tory candidates, Uppal and Kotecha have the maximum chance of winning in their constituencies of Wolverhampton South West and Coventry North-West respectively.
The Labour Party's tally also stands at five sitting MPs seeking re-election - Keith Vaz, sister Valerie Vaz, Virendra Sharma, Seema Malhotra and Lisa Nandy.
Among the Labour party's new group of prospective parliamentary candidates, Gill and Dhesi have a strong chance to be among the first British Sikhs to enter the House of Commons from Birmingham Edgbaston and Slough constituencies respectively.
British Sikhs have been campaigning to get the electorate to take notice of these Sikh candidates, who they hope will go on to make history as the first female Sikh MP (Gill) and first turbaned MP (Dhesi).
While many of the 10 Indian-origin MPs elected in May 2015 are defending quite comfortable margins this time, the changed Brexit reality since the lastelectionmeans a heightened sense of uncertainty.
If the opinion polls are to be believed, the ruling Conservative party is largely forecast to have a smoother ride under Theresa May's leadership than the opposition Labour.
Given the uncertainty, it is the ethnic minority vote that is believed to hold the key in many of the target or marginal seats, which are constituencies with a very slim majority for the sitting MP leaving it up for grabs for any party.
"We found that the Conservatives, Labour and the Liberal Democrats need the BME (black and minority ethnic) vote in 2017 to win their targets. Even considering current polling showing Theresa May's party ahead, failure to take a major slice of the BME vote could mean her Commons majority is much lower than predicted," forecasts advocacy group Operation Black Vote.
