Bit of background on this question;
A group raised a conflict of interest dispute against our group - we immediately took necessary steps to remedy this action. We let them know within a day that we were doing this so they were aware steps were being made, and by the end of the weekend we sent via email a full log of changes we had made (all communications so far had been made over the phone or in person).
We asked in this e-mail if they could confirm the above changes were satisfactory (for our own protection) and they have yet to respond. Then in person they have now stated that they will not be responding in writing.
Our issue is, we want this in our writing in case they attempt to take this further, however they've verbally stated (off the record) that they will not be putting anything into an email to us.
We are considering a follow-up email after 2-3 weeks requesting response within the e-mail, and that if they do not respond within X time we are within our rights to assume they agree.
My Question is:
Is there an appropriate amount of time that we can define which would have legal standing that unless they dispute further, we are able to assume that their 'silence' is 'agreement'. I suspect that would prompt a response from them though - but, what would be a reasonable amount of time to include in case this rears it's head at us in the future.
Thanks!
