Delegated Acts: Article 290 of the Lisbon Treaty introduces the novel concept of “delegated acts” to supplement or amend non-essential elements of framework legislation, i.e. issues of general scope.  On a case-by-case basis, the Council and European Parliament set the conditions for the delegation of power: objectives, content, scope and duration of the delegation are defined in each basic legal act.  The Council or European Parliament may revoke this delegation and a delegated act adopted by the Commission can only enter into force if no objection has been raised by one of the legislators within a time period set by the basic act.授权行为：《里斯本条约》第290条引入了“授权行为”的新概念，以补充或修改框架立法的非必要要素，即一般范围的问题。理事会和欧洲议会根据具体情况设定权力下放的条件：每项基本法律法案都规定了权力下放的目标、内容、范围和期限。理事会或欧洲议会可以撤销这一授权，并且只有在基本法案规定的期限内没有一位立法者提出反对意见的情况下，委员会通过的授权法案才能生效。
