whether a trial court can permit a lacuna in prosecution evidence to be filled up? Supreme Court said yes.

Cr.P.C. S.311: Lacuna Means inherent weakness or a latent wedge: After the defence and prosecution closed their evidence, the prosecution applied to resummon two of it’s already exmined witnessess, for proving it’s certain documents. Thus, a question arose, whether a trial court can permit a lacuna in prosecution evidence to be filled up? Upholding allowing the application, held that the conventional concept is that the court should not do so. But, then, what is meant by lacuna in a prosecution case, has to be understood before deciding the said question one way or the other.  Lacuna in the prosecution must be understood as the inherent weakness or a latent wedge in the matrix of the prosecution case. No party in a trial can be foreclosed from correcting errors. – Rajendra Prasad Vs. The Narcotic Cell, AIR 1999 SC 2292.
