The Supreme Court in Papua New Guinea has ruled that the mobile phone licence issued to the company, Digicel, is valid.
The Post Courier reports that Telikom has been attempting to have Digicel's licence taken away and went to court over the issue.
The National Court ruled in July last year that Digicel's licence is valid.
Telikom has appealed that decision.
The Supreme Court has now dismissed the appeal and confirmed the National Court's decision.
It also ordered Telikom pay the cost of the proceedings.
