The information includes commencement details for amending laws and details of any application, saving or transitional provisions that are not included in this compilation.\n\nThe amendment history in endnote 4 provides information about amendments at the provision (generally section or equivalent) level. It also includes information about any provision of the compiled law that has been repealed in accordance with a provision of the law.\n\nMisdescribed amendments\n\nA misdescribed amendment is an amendment that does not accurately describe the amendment to be made. If, despite the misdescription, the amendment can be given effect as intended, the amendment is incorporated into the compiled law and the abbreviation “(md)” added to the details of the amendment included in the amendment history.\n\nIf a misdescribed amendment cannot be given effect as intended, the abbreviation “(md not incorp)” is added to the details of the amendment included in the amendment history.\n\n> Note: Endnote 2—Abbreviation key\n\n|                                                | o = order(s)                        |\n| ---------------------------------------------- | ----------------------------------- |\n| ad = added or inserted                         | Ord = Ordinance                     |\n| am = amended                                   | orig = original                     |\n| amdt = amendment                               | par = paragraph(s)/subparagraph(s)  |\n| c = clause(s)                                  | /sub‑subparagraph(s)                |\n| C[x] = Compilation No. x                       | pres = present                      |\n| Ch = Chapter(s)                                | prev = previous                     |\n| def = definition(s)                            | (prev…) = previously                |\n| Dict = Dictionary                              | Pt = Part(s)                        |\n| disallowed = disallowed by Parliament          | r = regulation(s)/rule(s)           |\n| Div = Division(s)                              |                                     |\n| exp = expires/expired or ceases/ceased to have | reloc = relocated                   |\n| effect                                         | renum = renumbered                  |\n| F = Federal Register of Legislation            | rep = repealed                      |\n| gaz = gazette                                  | rs = repealed and substituted       |\n| LA = Legislation Act 2003                      | s = section(s)/subsection(s)        |\n| LIA = Legislative Instruments Act 2003         | Sch = Schedule(s)                   |\n| (md) = misdescribed amendment can be given     | Sdiv = Subdivision(s)               |\n| effect                                         | SLI = Select Legislative Instrument |\n| (md not incorp) = misdescribed amendment       | SR = Statutory Rules                |\n| cannot be given effect                         | Sub‑Ch = Sub‑Chapter(s)             |\n| mod = modified/modification                    | SubPt = Subpart(s)                  |\n| No. = Number(s)                                | underlining = whole or part not     |\n|                                                | commenced or to be commenced        |\n\n> Note: Endnote 3—Legislation history\n\n| Name                                                                                                    | Registration               | Commencement    | Application, saving and transitional provisions |\n| ------------------------------------------------------------------------------------------------------- | -------------------------- | --------------- | ----------------------------------------------- |\n| Statement of Principles concerning osteoarthritis (Balance of Probabilities) (No. 62 of 2017)           | 6 November 2017F2017L01442 | 4 December 2017 |                                                 |\n| Amendment Statement of Principles concerning osteoarthritis (Balance of Probabilities) (No. 74 of 2019) | 3 July 2019F2019L00959     | 22 July 2019    |                                                 |\n| Amendment Statement of Principles concerning osteoarthritis (Balance of Probabilities) (No. 41 of 2020) | 28 April 2020F2020L00503   | 25 May 2020     |                                                 |\n| Amendment Statement of Principles concerning osteoarthritis (Balance of Probabilities) (No. 77 of 2022) | 4 July 2022F2022L00942     | 25 July 2022    |                                                 |\n\n> Note: Endnote 4—Amendment history\n\n| Provision affected                                          | How affected       |\n| ----------------------------------------------------------- | ------------------ |\n| Section 2……………….                                            | rep LA s 48D       |\n| Section 4……………….                                            | rep LA s 48C       |\n| Subsection 7(2)………..                                        | rs.
