Smart Mobile's legal action against the communications regulator ComReg over its withdrawal of the fourth 3G licence on Tuesday has been adjourned for two weeks.
The High Court adjournment was requested by ComReg.
On Tuesday Smart Mobile obtained an interim injunction restraining ComReg from awarding the fourth 3G licence to any other company.
The 3G licence provides for a minimum of 53 per cent network coverage to be achieved by 2011. Vodafone, O2 and 3 Ireland hold the existing licences.
