Acceptance decision

https://www.accaglobal.com/gb/en/student/exam-support-resources/professional-exams-study-resources/p7/technical-articles/acceptance-decisions.html "Once a client has been accepted, the firm should consider the suitability of the specific engagement it has been asked to perform. In particular there may be ethical threats which mean that the engagement should not be accepted, in particular whether there are any threats to objectivity. Potential threats could arise for example, if members of the audit firm hold shares in the client or there are family relationships. If threats are discovered, it may not mean that the client must be turned down, as safeguards could potentially reduce the threats to an acceptable level." Should the ethical consideration consider before the client has been accepted or after that?
