( CNN ) -- A federal judge struck down key parts of a new Texas abortion law , considered among the most restrictive in the country , on Monday , one day before they were scheduled to take effect . The lawsuit -- filed in U.S. District Court in Austin by Planned Parenthood on behalf of more than a dozen women 's health care providers across Texas -- alleged the law violates the constitutional rights of women and puts unreasonable demands on doctors who perform abortions . The lawsuit specifically targets requirements under the new law that doctors obtain admitting privileges at a hospital within 30 miles of the clinic at which they 're providing abortion services , and usage controls on RU486 , a drug that induces abortions . U.S. District Judge Lee Yeakel blocked the law 's admitting privileges requirement , arguing that it `` places a substantial obstacle in the path of a woman seeking an abortion of a nonviable fetus and is thus an undue burden to her . '' He also blocked a part of the law that deals with medication-induced abortions but allowed restrictions on the same issue to move forward . Provisions such as requiring strict use under Food and Drug Administration protocol and mandatory follow-up visits remain in place . `` The medication-abortion provisions may not be enforced against any physician who determines , in appropriate medical judgment , to perform a medication-abortion using the off-label protocol for the preservation of the life or health of the mother , '' Yeakel wrote . Abortion-rights groups say the judge did not go far enough on the issue of medication-induced abortion , believing doctors should be able to use it with few restrictions . `` Today 's ruling marks an important victory for Texas women and sends a clear message to lawmakers : it is unconstitutional for politicians to pass laws that take personal , private decisions away from women and their doctors , '' Cecile Richards , president of Planned Parenthood Federation of America , said in a statement . `` While this ruling protects access to safe and legal abortion for women in many parts of the state , part of this ruling will make it impossible for many women to access medication abortion , which is safe and effective early in pregnancy , '' she said . Conservative groups were disappointed by the ruling . `` Blocking this law only puts vulnerable women in greater danger . We are very disturbed that a judge would partially block a law that is grounded in the latest science and in common sense , '' said Anna Higgins , director of the Center for Human Dignity at the Family Research Council . The bill originally failed to gain approval because of a Democratic filibuster led by state Sen. Wendy Davis . Texas Gov . Rick Perry then called the legislature into a second special session to continue consideration of the bill . In response to the judge 's ruling , Perry vowed he and others will keep fighting . If the state decides to appeal , the case would head next to the 5th Circuit Court of Appeals in New Orleans . `` Today 's decision will not stop our ongoing efforts to protect life and ensure the women of our state are n't exposed to any more of the abortion-mill horror stories that have made headlines recently , '' the governor said . He added : `` We will continue fighting to implement the laws passed by the duly-elected officials of our state , laws that reflect the will and values of Texans . '' Separately , the law prohibits abortions past 20 weeks of gestation . That ban takes effect , as scheduled , on Tuesday . CNN 's Bill Mears , Joe Sutton and Janet DiGiacomo contributed to this report .
