I came across this literature recently:
An Owner may apply for a Change of Name of a registered Greyhound by submitting to the GBGB the appropriate form duly completed, which form shall include details of existing and/or prospective Part-Owners of the Greyhound, where relevant.
Is "which form" correct in this example? Why does the noun "form" need to be repeated; isn't the word "which" supposed to imply a noun from the previous clause? If the noun being implied is ambiguous, is it standard practice to clarify it by repeating it after "which" or not?
