Missouri, Ex Rel. Walker v. Walker was a United States Supreme Court case that dealt with the issue of alimony. The case involved a husband and wife, both of whom were residents of Missouri. The husband had filed for divorce and sought alimony from his wife. The wife argued that the alimony should not be granted because the husband had abandoned her and their children. The Supreme Court held that the husband was not entitled to alimony because he had abandoned his wife and children. The Court noted that the husband had failed to provide any support for his family and had not even attempted to contact them. The Court also noted that the husband had not provided any evidence that he had made any effort to provide for his family. The Court concluded that the husband had not met his obligations to his family and was not entitled to alimony. The Court's decision in this case established that a husband who has abandoned his family is not entitled to alimony. The Court also established that a husband must make an effort to provide for his family in order to be eligible for alimony. This case is an important precedent in the area of family law and has been cited in numerous other cases.

In Missouri, Ex Rel. Walker v. Walker, the Supreme Court was asked to decide whether a court of equity had jurisdiction over a case involving an alleged breach of contract between two parties in which one party sought specific performance from the other. Justice Field dissented and argued that it was not within the power of courts of equity to grant relief for such cases because they lacked authority under state law to do so. He further noted that even if there were some legal basis for granting relief, it would be inappropriate as this type of dispute should be resolved through arbitration or by trial before a jury rather than by equitable remedies granted by a court. In conclusion, he concluded that while courts may have general jurisdiction over contracts disputes, they lack authority to provide specific performance in these types of cases and thus could not properly grant any form of relief requested in this particular case.
