Two Op-Eds on Nebraska's New Abortion Laws

LA Times (op-ed): Nebraska legislation aimed at undoing Roe vs. Wade, by Caitlin Borgmann:

Nebraska's Abortion Pain Prevention Act, signed into law last week, appears to have a quite reasonable aim: to prevent fetuses from feeling pain during abortions. In fact, the law, which bans abortions for women more than 20 weeks pregnant, is yet another attempt to undo Roe vs. Wade and abolish a woman's constitutional right to a pre-viability abortion. To do this, the law takes a disingenuous path, one well trodden by antiabortion legislation passed in the decades since Roe. . . .

Omaha World-Herald: New Nebraska abortion laws defy Constitution, by Caitlin Borgmann:

Nebraska’s new abortion laws the Pain-Capable Unborn Child Protection Act and a law requiring pre-abortion screening are unconstitutional under Roe v. Wade and Planned Parenthood v. Casey.

Indeed, it seems quite clear that the first law is intended to persuade Justice Anthony Kennedy, the U.S. Supreme Court’s swing vote on abortion, to jettison those decisions’ most fundamental premises. So what makes these laws unconstitutional?
