    Reported Cases 

    • Re M (Special Guardianship Order: Leave to Apply to Discharge) [2021] EWCA Civ 442

    This case clarifies the test to be used when applying for leave to discharge a Special Guardianship Order. There are two stages to this test. First, there must be a significant change of circumstances. If this test is met, then the the court must evaluate the prospects of success  of the application in the context of the effect on the child’s welfare of the application being heard or not heard. However the child’s welfare is not the paramount consideration. The degree of any change in circumstances is likely to linked to prospects of success. The greater the prospects of success, the more likely it is that leave will be granted.
