Judge Deady was a man of his times.  This is shown in the votes of the Oregonians after the Oregon Constitutional Convention.    

"In the fall voters faced three questions. Did they approve the constitution? They voted yes. Did they want slavery? They voted 7,727 no and 2,645 yes. Did they want freed African-Americans to live in Oregon? They voted eight to one against permitting their residency."  Oregon Blue Book.

Judge Deady wrote into law what Oregonians at the time wanted.
