The very convoluted amendments may be read via Parliament's website. In basic terms, the Speaker will certify whether a Bill (or a clause or a schedule) relates to either (a) England only or (b) to England and Wales. If the Speaker certifies that it does, then a new stage in the legislative process will apply. After Report Stage and before third reading, the Bill will have to be approved by a Grand Committee made up of MPs representing (as the case may be) either (a) English constituencies or (b) English and Welsh constituencies. Thus, the Grand Committee will have a veto over the Bill. The new process is helpfully shown in this diagram - (click on it for enlargement):
As the articles listed below show, this change is highly controversial in some quarters.
The role of the Speaker
may well prove to be far more complex than perhaps is realised at first glance. The Speaker has to consider not only whether the subject matter relates to England only (or to England and Wales) but he must also consider whether the subject matter is within the devolved legislative competence of the Scottish Parliament, the Welsh Assembly and the Northern Ireland Assembly.
It is here where legal problems might arise. The devolution legislation (e.g. Scotland Act 1998) contains provision for devolution questions to be settled by the Supreme Court of the UK. This has given rise to some difficult cases. The following are examples -
Martin v Most  UKSC 10)
Imperial Tobacco v Lord Advocate  UKSC 61
Agricultural Sector (Wales) Bill Reference  UKSC 43)
Where the precise boundaries of devolution lie is ultimately a LEGAL question and this could put the Speaker in a very difficult situation. It is not clear how problems would be resolved if the Speaker's decision on a Bill were to be challenged.
A further problem for the Speaker might be that the Standing Orders - 83J(6) - state:
All MPs will continue to be able to speak and vote at stages other than the new Grand Committee stage. Thus, the actual outcome is certainly NOT English Votes only for English laws. Effectively, the new process gives English MPs the right to veto English only laws.
