The government now faces refunding tens of millions of pounds to those charged over the last four years.
The public sector union, Unison, won the landmark court victory against the government after arguing they discriminated against women and other groups of workers.
Roger Kiska, Legal Counsel for the Christian Legal Centre told Premier that the courts are for the benefit of all people.
During News Hour he said: "If you look at the number of cases that were filed before 2013 compared to after 2013 when the fee schedule fell into place, it was less than half.
"So these fees really did have a chilling effect on people seeking their rights in the employment tribunal."
As a result of the Supreme Court unanimously ruling the government was acting unlawfully and unconstitutionally, the government will have to take immediate steps to stop charging the controversial fees of up to £1,200 for taking a case to tribunal.
Unison said the government will also have to refund more than £27 million to the thousands of people charged for taking claims to tribunal since July 2013, when the Lord Chancellor at the time, Chris Grayling, introduced the fees.
The Trades Union Congress' general secretary, Frances O'Grady said of the ruling: "This is a massive win for working people.
"Too many low-paid workers couldn't afford to uphold their rights at work, even when they've faced harassment or have been sacked unfairly."
Kiska told Premier that today's move will help many Christians who've had their rights 'violated'.
He added: "We're grateful to the court for the decision. We believe that access to justice at an affordable rate is important so we stand by the court in its decision."
