Except where the reasons are announced orally at the hearing, the Court normally reserves its decision. While the case is on reserve, the judges spend a considerable amount of time producing detailed written reasons for judgment. That process may take several months, or over a year. There is normally a majority decision, but judges who disagree with the majority can write a minority opinion, dissenting in whole or in part from the majority. Any judge can write a concurring opinion, agreeing with either the majority or the minority, or setting out the judge's own separate position. While the reasons for judgment are being developed, they may be rewritten several times. There may be a significant amount of continued debate over how the propositions should be articulated and what should be left out. In the more divided cases, there is a possibility that a judge may switch sides during the process and change the outcome of the case.
