Case laws for acquittal in sec.420, 468 and 471 ipc required

Acqittal is possible in even the most serious offences depending on how good your attorney is and how weak the evidence is. Excellent attorney's weaken the evidence. I was reading one clearcut case case of Murder but Attorney/Lawyer harped on a very small sub clause of the Indian Evidence Act and .Vardrajan J and Justice Murtaza Ali and Justice Sabyachi Mukerjhee converted it into a case of Suicide. Since all the three judges concurred, I'm none to comment on this judgment.[1984 4 SCC, p 116- 215]

sec.195(1) (b) (ii) of code of criminal procedure provision affecting case laws
