The Illinois Motion for Review of Certification is a legal petition in the state of Illinois that allows parties to request a review of the certification of a class action lawsuit. This motion is typically filed by an aggrieved party who believes that the certification of the class was improperly granted and seeks to have it reviewed by the court. The main purpose of the Motion for Review of Certification is to challenge the decision made by the court to certify a class. It is a critical step in the class action process, as certification allows the lawsuit to proceed on behalf of a group of individuals who share common claims. By filing this motion, the moving party aims to establish that the legal requirements for class certification are not met or that the certification decision was somehow flawed. There are different types of Motions for Review of Certification that can be filed in Illinois, depending on the specific grounds for challenging the certification decision. Some common types include: 1. Lack of Tuberosity: This motion argues that the class does not meet the requirement of tuberosity, which means that the class is not large enough to warrant a class action lawsuit. The moving party must demonstrate that there are too few members in the class to effectively prosecute the claims collectively. 2. Inadequate Representation: This motion asserts that the named representative(s) of the class are not suitable and do not adequately represent the interests of the entire class. The moving party must show that the representative(s) have conflicts of interest or are otherwise unfit to act on behalf of the class. 3. Commonality and Typicality: This motion challenges the court's finding that the claims of the class members share common questions of law or fact and that the claims of the named representative(s) are typical of those of the entire class. The moving party must establish that there are significant differences among the class members' claims that prevent them from being resolved collectively. 4. Superiority and Manageability: This motion argues that a class action is not the superior method to resolve the claims and that individual lawsuits would be more appropriate. The moving party must prove that the class action would create significant manageability issues or administrative burdens that outweigh the benefits of resolving the claims collectively. In conclusion, the Illinois Motion for Review of Certification is a legal mechanism used to challenge the certification of a class action lawsuit. It allows parties to request a review of the certification decision by raising various grounds, such as lack of tuberosity, inadequate representation, lack of commonality and typicality, or issues of manageability. Filing this motion plays a crucial role in shaping the trajectory of a class action lawsuit in Illinois.
