Stamping is different scenario...I do believe, ticket status b4 cancellation should be taken but moderation strictly follows ticket status after charting (Was RAC/CNF & get canceled, it should be stamped canceled)!! Stamping here may have been done based on last status b4 cancellation!!
If Ticket presented after charting @ journey commencing station (b4 train DEP or time frame defined after DEP), is a proof that journey nt been undertaken & clerk redeem amount (as PRS Ticket amount cant be credited into any account but live to person present)!! Yes, if Ticket been presented after charting @ station where chance of journey undertaken arise, TDR required!!

more... E-Ticket, journey commenced or not needs verification, as its not live but online & after charting, TDR process gets follows (TTE chart marking)!!
