South Africa's Premier League (PSL) has opposed ICASA's plans to amend the Sports Distribution Services Regulations.
Amended regulations aim to make great sporting events more available for all South Africans.
Currently, many sports events, including football matches, are only available to DStv's SuperStore subscribers.
Regulations will disrupt the DStv monopoly on the direct broadcasting of sporting events, which, according to ICASA, is in line with the Electronic Communications Act.
DStv's parental MultiChoice, however, is by far the largest investor in South African sport – and currently spends about R2 billion a year on sports broadcasting rights.
If their ability to generate revenue from DStv and SuperSport is affected by the exclusion of exclusive rights, these costs may be affected.
As reported from the Sunday Times, PSL said that if the regulations were passed, their league would close.
"ICASA claims to make these changes in the public interest to prohibit subscription services from being granted exclusive rights," PSL chairman Irwin Khoza said.
He said that what is not being considered is that PSL receives 80% of its revenue from SuperSport.
The current Chief Executive of the Football Association of Rass Paul said they can not agree with the proposals made by ICASA and will "resist fiercely".
SA Rugby and SA Cricket also submitted comments to ICASA on the changes to the regulation.
Cricket CEO Thabang Moroe said "it is not up to us to answer whether these provisions are necessary or not."
MultiChoice said they are currently reviewing the draft laws and will provide a comprehensive response.
