India Inc may have made waves across the world for its entrepreneurial spirit in 2007, but back home it made headlines for court battles to settle business rivalry and challenge government decisions.Titans of the Indian industry will try to settle scores and resolve issues when courts start opening from tomorrow after a two week vacation.Family feuds involving the Bajaj brothers (Rahul and Shishir), Kanwars (of Apollo Tyres), Singhals (of Bhusan Steel) will resume before the Company Law Board, while a battle involving Tatas and Birlas over Idea Cellular will play itself out before the Supreme Court during this year.The Delhi High Court as well the telecom appellate tribunal TDSAT will start hearing the issue of spectrum allocation and permission to dual technology that reached its crescendo at the turn of the year.The spectrum controversy took wings in October last year when the government allowed Anil Ambani-led Reliance Communications to operate in the lucrative GSM segment under the dual technology clause and new norms for spectrum allocation as recommended by sector regulator TRAI.Cellular Operators Association of India, the lobby of GSM operators such as Bharti, challenged the norms in tribunal TDSAT and Delhi High Court, but did not get any relief.Besides, anti-monopoly watchdog MRTPC would also hear a matter pertaining to possible cartelisation in the GSM mobile industry, which saw the three big players simultaneously raise mobile tariffs by 20% in August last year. TDSAT too is scrutinising the matter.Elsewhere, the Delhi High Court is expected to continue hearing rebel cricket league ICL's petition seeking to protect its cricketers from punitive action.(Reported by Kumar Rahul and Anand Raj)
