John, Dinesh's follow up answer indicates she was abandoned by her agent. Shame on them. If they are not working for their client, I don't think they deserve a commission. Yes, we all have to work together, but if her agent hasn't bothered to stay in touch and particularly didn't notify their buyer that the house she was interested in had come back on the market and at a lower price than that agent is not doing their job.
A far as procuring cause, I think you will see that most definitions of procuring cause will state that it is an "uninterrupted" series of events that leads to a successful transaction. If you read the ethics and arbitration manual I think you will find a number of questions that go something like:
1.Did the original introduction of the purchaser or tenant to the property start an uninterrupted series of events leading to the sale (or to any other intended objective of the transaction) or was the series of events hindered or interrupted in any way?
2.If there was an interruption or break in the original series of events, how was it caused, and by whom?
3.Did the broker making the initial introduction to the property maintain contact with the purchaser or tenant or could the broker's inaction have reasonably been viewed by the buyer or tenant as the broker having withdrawn from the transaction?
4.Did the broker making the initial introduction to the property engage in conduct, (or fail to take some action) which caused the purchaser or tenant to choose to utilize the services of another broker?
5.Was the entry of any cooperating broker into the transaction an intrusion into an existing relationship between the purchaser and another broker, or was it the result of abandonment or estrangement of the purchaser, or was it at the request of the purchaser?
6.Did the cooperating broker (or second cooperating broker) initiate a separate series of events, unrelated to and not dependent on any other broker's efforts, which led to the successful transaction?
Yes John, I understand Karma, but what about the Karma between Dinesh and the first agent who appears to have abandoned her?
