During the Democratic Revolution of 1954, the unions inflicted a decisive blow against the giants and the sugar industry declined after Hawaii became a state in 1959; so did each of the Big Five companies. The greatest post-statehood challenge came as the U.S. Department of Justice challenged the ownership of Matson Navigation Company by four of the five companies (all except Theo H. Davies). The lawsuit was settled when the four companies agreed not to share officers, executives, and directors. Alexander and Baldwin eventually bought out the other three stakes in Matson in 1964.
