57 In Rankin's case (above), Gillard J considered the law of condonation at [352 ff]. He said:
"352 An employer who has full knowledge of the misconduct of an employee, and who makes a decision to continue to employ the employee, cannot at a later date, unless of course other facts come to his knowledge, dismiss him summarily on the basis of the employee's known misconduct. It is said that the employer has waived his right to dismiss the employee summarily, and thereby condones the misconduct.
353 In Phillips v Foxall (1872) LR 7 QB 666, Blackburn J said (at 680):
'Now the law gives the master the right to terminate the employment of a service on his discovering that the servant is guilty of fraud. He is not bound to dismiss him, and if he elects, after knowledge of the fraud, to continue him in his service, he cannot at any subsequent time dismiss him on account of that which he has waived or condoned. This right the master may use for his own protection.'
354 It is noted that his Lordship used the words "elects", "waive" and "condone" as meaning the same thing. There has been much written in the past 100 years concerning those three expressions in the law, and it is not for me to add to the material, on what each word means and their application. It is clear that no such waiver, condonation or election can take place until the employer has full knowledge of the misconduct. Hence, it must follow that an employer would not be held to have condoned the wrongdoing, where he believed the employee's denial and subsequently found out the truth. See Federal Supply Co v Angehrn (1910) 103 LT 150 (PC).
355 In that case, the Privy Council said (at 152):
'The word "condonation", though used in some of the authorities cited by most distinguished judges, is not quite happily chosen. In the cases of Phillips v Foxall and Boston Deep Sea Fishing and Ice Co , so much relied upon by the respondents, the word is used as applicable to a case where a master with full knowledge of a servant's misconduct continues to retain him in his, the master's, service. It is likened to the case of a man who, knowing he has a legal right to do either of two things, determines or elects to do one of them in preference to the other, and also likened to the case of a man who, knowing that a forfeiture has been worked, and that he has the legal right to take advantage of it, deliberately abandons that right - that is, waives the forfeiture . In these cases, however, to which " condonation" is compared, the burden of proving that the election had been made or the forfeiture was waived would rest upon him who relied upon the one or the other, and so it is with condonation. The master must be fully aware that the servant has by his misconduct forfeited the right to be continued in his master's service, which is the correlative of the master's right to dismiss him, before he can be held to have waived that forfeiture.'
