FILA had been supplying skating uniforms since October 2012.

In protest, FILA released the results of a study last week showing its products were lighter and offered less air resistance.

FILA also said Hunter's uniforms will cost skaters more than a second off their times.

Then on Monday, FILA said it has filed a court injunction against the KSU's uniform supplier selection process, saying the organization has violated the spirit of fair play.

The KSU tested uniforms from three companies -- FILA, Hunter and Mizuno -- on eight speed skaters and short track speed skaters, and seven of those eight preferred Hunter. The KSU has maintained that its selection process has been clean since the athletes themselves picked Hunter.

FILA countered that using the athletes' comfort level with uniforms was highly unreliable and subjective, and since the tests were done behind closed doors, it was difficult to verify their transparency and fairness.

FILA also accused the KSU of limiting the company's rights as the national team corporate sponsor without reasonable grounds, and added the KSU also stripped FILA of an opportunity to enter the proper bidding to remain as a sponsor by making unreasonable demands at the last minute. FILA claimed that the KSU opened the bidding only to the companies that had previous business dealings with Hunter.

Meanwhile, Hunter accused FILA of providing "biased data" and packaging them as facts for South Korean athletes and the public.

"We will not tolerate such defamation using distorted information from unreliable tests," Hunter said through Bravo & New, which holds the Dutch company's local distribution rights.

"Being lighter and having less air resistance don't always equal the best products. We're preparing for a legal step since the malicious acts of disparaging our products violates sportsmanship." (Yonhap)
