The bill will now go to the Legislative Council.
Speaking during the second reading debate, Sir Charles said that the Liberal Party would allow its members a free vote.
He believed that the ban, imposed in 1968, had considerable effects on the practice of scientology in W.A. and that it would be wrong to remove the Scientology Act from the Statute Book.
He did not regard the matter as being one of freedom of religion or freedom of worship. Many people wanted action to be taken against scientology because the practice was so cynical and diabolical.
Earlier, Mr A. Mensaros (Lib., Floreat) said that the Minister for Health, Mr Davies, had gone against the advice of the Director of Mental Health, Dr A.S. Ellis, in moving to lift the ban.
Mr Mensaros said: "I think we should have had very convincing reasons presented to us by the Minister why Dr Ellis was wrong and the lay members of the Cabinet were right."
People were under the impression that the existing Act banned scientology. This was not so. The fact that scientologists still exist should be proof of this, he said.
The Bill passed all stages without amendment.
