RAISING ISSUE(S) SUO MOTU: Effect of raising an issue suo motu without hearing from the parties 

"Judicial authorities are well settled that once a Court raises an issue suo motu as in the instant appeal wherein the Court raised the issue of issuance of notice suo motu in his ruling on the admissibility of a document without affording the parties opportunity of being heard, the proceeding conducted thereon would be a nullity. In other words, the Court would be in error if it proceed to resolve such issue without affording the parties an opportunity of addressing it on the said issue.
