The Institute for Justice's Jeff Rowes had a great op-ed in Saturday's Wall Street Journal explaining that both liberal and conservative judges are guilty of showing too much deference to the legislative and executive branches:
Many conservatives who think of themselves as proponents of limited government would be surprised to discover that conservative judges begin their constitutional analyses in almost every context by placing a thumb firmly on the government side of the scale. It's called "judicial deference." Many liberals, who take pride in being "empathetic," would be surprised to learn that liberal judges also subscribe to judicial deference….
It all began in the late 1930s, when the Supreme Court opened the floodgates for New Deal economic regulation. In essence, conservatives have adopted the big-government agenda of that era. The liberal-conservative consensus explains why nomination fights focus on a few "culture war" issues such as gay marriage or guns. Liberals and conservatives squabble over these esoteric questions because there is such harmonious accord on everything else.
The time-honored justification for judicial deference is that when courts refuse to enforce property rights and allow economic liberties to be trampled by legislatures they are showing respect for the democratic process. But this notion is not faithful to the duty of the judiciary. The Constitution's framers understood that legislatures are as much nests of vice as of virtue. That is why they went to such lengths to define the limits of government, set forth our rights broadly, and create an independent, co-equal branch of government to protect those rights.
