That is, the committee considers whether the Ministers have the power to make that SSI under the enabling Act, whether the Scottish Parliament has the power to make law in that area under the Scotland Acts, and whether the provisions of the SSI are clear, consistent, and free of typographical errors. The DPLRC and other committees report back to Parliament, which applies a varying level of scrutiny depending on the exact procedure for that SSI. Negative procedure A negative SSI is an SSI subject to negative procedure. Such SSIs must be laid before Parliament at least 28 days before they come into force, and may be annulled by Parliament resolution within 40 days of their being laid. If an SSI is annulled after it comes into force, it ceases to have force from the date of annulment. Affirmative procedure An affirmative SSI is subject to affirmative procedure. These SSIs must be approved by resolution of Parliament before they can come into force. Special parliamentary procedure Some SSIs are subject to special parliamentary procedure. These are so-called special procedure orders (SPOs), and differ from SSIs subject to other types of procedure in that notice of SPOs must be posted in the Edinburgh Gazette (or a local newspaper, if the SPO relates to a particular area) and in that members of the public may object to an SPO. If an SPO is objected to, it must be laid before the Parliament with its objections and then confirmed by an Act of the Scottish Parliament. If no objections are made, the Parliament may annul the order within 40 days of its being laid. If no objections are made and the Parliament does not annul the SPO, the SPO comes into force at the end of the 40-day period or at a later date if the SPO so specifies. Other procedures In addition to the above procedures, which are defined by the Interpretation and Legislative Reform (Scotland) Act 2010, an enabling Act may specify its own procedure for making SSIs. SSIs made under another procedure must be laid before Parliament "as soon as practicable after [they are] made," with some exemptions. As of October 2016, the exempted enactments are: Examples of these other procedures are laid-only procedure, where an SSI is laid before Parliament but cannot be rejected; and super-affirmative procedure, where a draft SSI must be subject to a formal consultation or other
