Indian Marathon Age Limits Lawsuit

The AP reports that the coach of a four-year-old Indian Marathon runner is challenging his pupil's exclusion from a marathon in court. I'm not sure what India's antitrust laws would say about this age-based exclusion. I think most common-sense observers would distinguish this case from Maurice Clarett's case based on the fact that this kid is only four. Although it does point to a potentially untapped argument for leagues seeking to defend age exclusions: that allowing someone under the age of majority to participate amounts to child labor in violation of international human rights accords?
