During an 18-year tenure on the Supreme Court, Justice David H. Souter migrated from conservative to moderate to liberal, leaving opinions across the political spectrum on divisive issues like abortion, property rights and the separation of church and state.

Planned Parenthood vs. Casey (1992)
In a bitter 5-4 vote upholding Roe vs. Wade and a woman's right to seek an abortion, Souter was one of three authors for the majority who outlined a new standard for determining whether an "undue burden" was imposed by state regulations requiring a married woman to inform her husband of her intent.
Souter, veering from his early propensity to vote with the high court's conservatives, wrote that to obstruct a woman's choice with state requirements for notification and informed consent would amount to "surrender to political pressure," and that overturning a watershed decision like Roe vs. Wade would "subvert the court's legitimacy beyond any serious question."
"Some progressive colleagues thought he'd be an avatar of the right, that he would change reproductive freedom," said Simon Lazarus of the Federal Rights Project, adding that he attributed Souter's independence to his roots in the more moderate Republican community of the Northeast.

New London vs. Kelo (2005)
When the city of New London, Conn., used its eminent domain authority to seize private property to sell to developers in hopes of spurring economic revival, Souter sided with the court's liberal faction in the 5-4 ruling.
Although it was Justice John Paul Stevens who wrote the opinion justifying the land transfer as a qualified "public use" of private real estate under the Takings Clause of the 5th Amendment, opponents of the seizure turned their wrath on Souter.
New Hampshire libertarians waged a fruitless campaign to seize the justice's "blighted" home in Weare, N.H., via eminent domain to build a "Lost Liberty Hotel" and "Just Desserts Cafe."
Souter's departure from traditional conservative values, such as property rights, made him a "stealth justice" who seldom voted with fellow Republican appointees, said Ilya Shapiro, a fellow at the Center for Constitutional Studies and editor of the Cato Institute's Supreme Court Review.
