“Reasonable cause” for the purpose of application of Section 271C in the backdrop of Section 273B has been explained by the Hon’ble Delhi High Court in the case of Woodward Governors India (P) Ltd. Vs. CIT (2002) 253 ITR 0745 to mean a probable cause, an honest belief founded on reasonable grounds, of the existence of a state of circumstances, which assuming them to be true, would reasonably lead any ordinarily prudent and cautious man, placed in the position of the person concerned to come to the conclusion that same was the right thing to do. The cause should not be found to be frivolous, without substance or foundation.
