In any Govt.office letters are signed by the 'office in -charge' for making outward correspondence.The Concerned clerk looking after 'inward- outward correspondence' records each letter in an ' outward register' serially under the date on which it is actually sent out from office and the entry is made in the form of - entry serial number,subject of letter,to whome sent,postage ticket's amount.If through oversight the clerk forgets to record the letter in the register and later he makes entry and gives serial number for example; 3a in between 3and 4 say in serial numbers 1,2,3,4.(there being no space after number 4.After 4 there is a next date) ; and dispatches letter under that number .Please guide whether this is a forgery ?
