Non-cts cheque issued before 2010

A cheque is always and a cheque can be presented through other ways for encashment.  If clearing is not possible, it ca be presented as outward cheque for collection by post to the bank branch by the receiving bank.  Such cheques are not accepted in clearing and it is only the date of the cheque as appearing at the time of presentation that is valid while making payment.
