if it is indicative and suggestive of some unfair practice by the investigating agency for the purpose of introducing a got up witness to falsely support the prosecution case". This has been reiterated by the Supreme Court in Ganesh Bhavan Patel v. State of Maharashtra, 1978 KHC 637 : AIR 1979 SC 135 : 1978 (4) SCC 371 : 1979 SCC (Cri) 1 : 1979 CriLJ 51 in the following words: "Delay may not, by itself, amount to serious infirmity in the prosecution case. But it may assume such a character if thereare concomitant circumstances to suggest that the investigator was deliberately marking time with a view to decide about the shape to be given to the case and the eye witnesses to be introduced". It added: If the circumstances of the case lead to "the conclusion that the prosecution story was conceived and constructed after a good deal of deliberation and delay in a shady setting, highly redolent of doubt and suspicion", it is fatal. The same view has been taken by the Supreme Court in Banti @ Guddu v. State of Madhya Pradesh, 2004 KHC 372 : 2004 (1) SCC 414 : AIR 2004 SC 261 : 2004 SCC (Cri) 294 : 2004 CriLJ 372 and Surajit Sarkar v.
