"18 Mr Jones fairly told us that if he had known that the applicant was pregnant she would not have been dismissed. In view of his earlier enquiry in that respect and the respondent's disciplinary procedure which provides for investigation and formal interview there is no doubt that the respondent should have been able to establish that the reason for the applicant's absence was her pregnancy."
"17 We are satisfied that the applicant was not dismissed solely because she was pregnant but are unanimous in our decision that her dismissal, which was not in any way in accordance with the respondent's disciplinary procedures, was connected with her pregnancy in that it was a dismissal whilst she was on certificated sick leave for depression caused by her pregnancy. To have acted fairly the respondent should have investigated the reason for her absence and depression and been satisfied that she was not pregnant and was either wilfully absenting herself or incapable of sustained employment."
"(1) An employee shall be treated for the purposes of this Part as unfairly dismissed if the reason or principal reason for her dismissal is that she is pregnant or is any other reason connected with her pregnancy ..."
"It must be shown in this case that the dismissal was because of the pregnancy or for another reason connected with the pregnancy. If this section is relied on, it seems to us essential that it be shown that the employers knew or believed that the woman was pregnant or that they were dismissing her for a reason connected with her pregnancy. If they do not know of the pregnancy, or do not believe that the pregnancy exists, it does not seem to us that it is possible for the employers to have as their reason for dismissal that the woman was pregnant. In a case where it is said that the reason for the dismissal is another reason connected with her pregnancy, not the pregnancy itself, it seems to us that the employers have to know the facts alleged by the employee as grounding the reason and also to know or believe that those facts relied upon are connected with the woman's pregnancy."
" ... If the reason was unjustified at that time, [and we interpolate that that was the time at which the notice took effect] then it was immaterial that justification may have existed when the notice was given."
