Though it was a case dealing with negative covenant that was operative during the employment period counsel pointed out that entire case law Indian as well as English was discussed and this Court at page 389 of the report observed thus: "The result of the above discussion is that considerations against restrictive covenants are different in cases where the restriction is to apply during the period after the termination of the contract than those in cases where it is to operate during the period of the contract." 1285 Tulzapurkar, J.) According to counsel the very fact that this Court has observed that considerations qua post service restrictions are different from those that are to be considered in cases of restrictions during the employment suggests that perhaps a rigorous test of reasonableness may have to be adopted in the former cases but there would be cases where post service restrictions, if reasonable, even after applying the rigorous tests may be valid as not falling under section 27 of the Act, it was, therefore, not correct to say that all post service restrictions were void.
