No conviction on the basis of surmises and conjectures or suspicion howsoever grave it may be

There can be no conviction on the basis of surmises and conjectures or suspicion howsoever grave it may be. Strong suspicion, strong coincidences and grave doubt cannot take the place of legal proof.

  In para 14 of its judgment Hon'ble Supreme court in case of Digamber Vaishnav and another vs State of Chandigarh (2019) 4 SCC 522, has held as under:

"14. One of the fundamental principles of criminal jurisprudence is undeniably that the burden of proof squarely rests on the prosecution and that the general burden never shifts. There can be no conviction on the basis of surmises and conjectures or suspicion howsoever grave it may be. Strong suspicion, strong coincidences and grave doubt cannot take the place of legal proof. The onus of prosecution can't be discharged by referring to very strong suspicion and existence of highly suspicious factors to inculpate the accused nor falsity of defence could take the place of proof which the prosecution has to establish in order to succeed, though a false plea by the defence at best, be considered as an addition circumstance if other circumstances unfailingly point to the guilt."

Objection to admissibility of electronic evidence without compliance of sec.65B can be raised in appeal even if not raised in the trial

Whats is the difference between objection to admissibility of document and objection to mode of proof?

What are its consequences?

If electronic evidence is admitted and exhibited in evidence then its admissibility can be raised in appeal even if it is not objected in the trial.
