14.7 Family Relationship – Reliance placed by the DG on family relationship between partners of OP-2, OP-4 and OP-5 is not sustainable due to long history of family disputes amongst them. First of all, such evidence cannot be relied upon against any other OPs than OP-2, OP-4 and OP-5. Further, OP-2 and OP-5 on one hand and OP-4 on the other have different control and management. Even though their partners are related, but due to long history of family disputes, their firms are fierce rivals. Their partners have even filed cases against each other in courts. Similarly though partners of OP-4 and OP-5 are brothers, but they are not on good terms. The DG has not even found any evidence of interaction between the family members who are partners in OP-2, OP-4 and OP-5. The sole point of interaction between the said OPs was Mr. Tapan Mukherjee, who was earlier employed with OP-4 but shifted to OP-2 after family disputes arose. Moreover, such interaction taking place through Mr. Tapan Mukherjee was only with regard to hire and lease of trucks. Ms. Shashikala Khandelwal, wife of partner in OP-5 namely Mr. Bimal Kumar Khandelwal did not surrender her shares in OP-4 because Mr. Kanhaiyalal Khandelwal, partner in OP-4, did not surrender his share in certain properties of Mr. Bimal Kumar Khandelwal. Between OP-2 and OP-4, there are no common partners. Hence, there was no collusion between OP-2, OP-4 and OP-5. OP-4 and OP-5 have not even been participating in the same tenders. In support of such contention, reliance has been placed upon Narendra Explosives (supra) .
