Principle: Every agreement, of which the object or consideration is opposed to public policy, is void. An agreement which has the tendency to injure public interest or public welfare is one against public policy. What constitutes an injury to public interest or public welfare would depend upon the times and the circumstances. Facts: ‘A’ promises to obtain for ‘B’ an employment in the public service, and ‘B’ promises to pay rupees 5,00,000/- to ‘A’.
