Claim 7:
8. A system for processing an electronic payment transaction, comprising at least one processor of an issuer computing system, the at least one processor programmed or configured to:
generate a plurality of fraud detection rules comprising at least one automatic decline fraud detection rule and a first case creation fraud detection rule;
electronically communicate the plurality of fraud detection rules to a rules processor associated with a case management system;
store, in a fraud rules database associated with the computing device of the case management system, the plurality of fraud detection rules;
receive a plurality of transaction requests, wherein the requests comprise requests to authorize transactions initiated in real time by a computing device associated with one or more merchants;
determine whether to authorize each transaction request of the plurality of transaction requests based on the rules processor processing each transaction based on the plurality of fraud detection rules, wherein the rules processor is caused to:
determine whether the transaction satisfies the first case creation fraud detection rule or the at least one automatic decline fraud detection rule,
generate a case record for each transaction determined to satisfy the first case creation fraud detection rule, wherein each case record indicates that its respective transaction requires further analysis to determine if the transaction is fraudulent,
automatically decline each transaction determined to satisfy the at least one automatic decline fraud detection rule, and
store the case record for each transaction determined to satisfy the first case creation fraud detection rule in a fraud processing queue such that the fraud processing queue comprises a first plurality of queued transactions that were not automatically declined and have not been authorized, the first plurality of queued transactions corresponding to a first plurality of case records, wherein each case record is stored in a data structure; and
generate at least one second fraud detection rule comprising a second case creation fraud detection rule that supersedes the first case creation fraud detection rule;

communicate in real time the at least one second fraud detection rule to the rules processor before the first plurality of queued transactions are further analyzed, the at least one second fraud detection rule configured to cause the rules processor to:
determine whether each case record in the queue satisfies the second case creation fraud detection rule,
delete each case record in the queue that does not satisfy the second case creation fraud detection rule, and
further analyze the remaining case records in the fraud processing queue that are not deleted.
