DES MOINES, Iowa (AP) — An Iowa woman is asking the U.S. Supreme Court to consider striking down surrogacy contracts as a violation of the constitutional rights of surrogate mothers and their babies. In an appeal of a February Iowa Supreme Court ruling, the woman asks the nation’s highest court to hear her case and consider whether surrogacy contracts affirmed in several states including Iowa, California, New Hampshire, Virginia, and Washington can be upheld.

The woman is identified in court documents as T.B. She entered into a surrogacy contract with Paul and Chantele Montover in 2016, but she decided she wanted to keep the baby after the relationship soured. The Montovers have raised now-23-month-old girl since birth. The Supreme Court is expected to decide by this fall whether to consider the case.
