Can an appeal apply in the matter of the engineer?

Dear Editor,

An appeal in the disposed matter of one who allegedly exposed himself is being made.  Can the same appeal principle apply in the disposed matter of the engineer who was accused of killing his fiancé?  Can a closer look be taken of the case to see whether elements were missed that might just justify an appeal?  It is might be worth the time and effort and at least some form of justice to the deceased might be given. The frequent instances of persons going free because of poor investigations and prosecution is tantamount to justice denied.  This is poor comfort to those seeking justice.

Sincerely,

Shamshun Mohamed
