Career
Charles Marks was appointed to the Queensland Legislative Council on 8 November 1888. Although a lifetime appointment, he resigned on 6 January 1892, as he was facing bankruptcy proceedings in relation to the RubyAnna sugar company of which he was a partner. However, he was able to satisfy his creditors and was reappointed to the Council approximately two months later on 11 March 1892.
He then remained on the Council until it was abolished on 23 March 1922.
