Is it necessary to conclude a formal written agreement for the application of antitrust law with respect to vertical restraints, or can the applicable rules be used by an informal or un written agreement? In practice, the ICC is generally not charged if market inecration is not demonstrated. For example, the ICC recently rejected allegations of vertical restraints and abuse of a dominant market position with respect to power purchase agreements between NTPC Limited (a company that operates in power generation) and Tata Power Delhi Distribution Limited (an electricity distribution company). The ICC was invited to examine the exclusions resulting from the duration of the power purchase agreements concluded by NTPC Limited, in particular whether the engagement of new undertakings prohibited entry into the electricity generation market. . . .
