Judge Rob La Grange struck the matter off the roll as it lacked urgency.
Amcu approached the court in a bid to prevent Anglo American Platinum (Amplats) and Impala from conveying a pay offer settlement to workers.
The union also wanted to prevent Impala from conducting a survey of whether workers want to return to work.
Amcu members at Lonmin, Impala and Amplats downed tools on January 23 demanding a basic monthly salary of R12,500.
They rejected the companies’ offer that would bring their cash remuneration to R12,500 by July 2017.
The strike, now on its 130th day, has cost the companies over R20 billion in revenue and workers over R9bn in earnings according to website www.platinumwagenegotiations.co.za, created by the companies.
