The document discusses the definitions and types of decrees and orders according to the Code of Civil Procedure, 1908. It defines a decree as the formal expression of an adjudication by a court determining the rights of parties regarding matters in controversy in a suit. A decree must be conclusive in nature. There are two types of decrees: preliminary and final. An order is defined as a formal expression of a court's decision that is not a decree. Key differences between decrees and orders are that decrees determine rights conclusively, there can only be one decree per suit, and all decrees are appealable unless expressly barred.
