Was the expulsion of pregnant police recruits fair?

NPS says the decision of expelling pregnant police was not displinary action.[TNX]

The National Police Service has clarified that the decision was not a disciplinary action, and two it was made to protect the health of both the recruits and their unborn babies, who obviously could not withstand the caliber of training that lasts six months.

The criticism of the move by some rights activists is just unnecessary and a waste of time. It is not the first time pregnant recruits have been sent home from a police training college. That has been the norm over the years.
