# Interpretation Act 1889

The Interpretation Act 1889 (52 & 53 Vict. c. 63) was an act of the Parliament of the United Kingdom that consolidated enactments relating to statutory construction and provided definitions to shorten the language used in acts of Parliament.
In Northern Ireland, Section 48(2) of the Interpretation Act (Northern Ireland) 1954 provided that without prejudice to 48(1) of that act, the Interpretation Act 1889 was to cease to apply to the interpretation of enactments. The whole Act, except paragraphs (4), (5) and (14) of section 13 in their application to Northern Ireland, was repealed by section 25(1) of, and Schedule 3 to, the Interpretation Act 1978.
In the Republic of Ireland, the application of the Interpretation Act 1889 was restricted to pre-1924 legislation by the Interpretation Act 1923, and repealed by the Interpretation Act 2005.

## Background

In the United Kingdom, acts of Parliament remain in force until expressly repealed. Blackstone's Commentaries on the Laws of England, published in the late 18th-century, raised questions about the system and structure of the common law and the poor drafting and disorder of the existing statute book.
In 1806, the Commission on Public Records passed a resolution requesting the production of a report on the best mode of reducing the volume of the statute book. From 1810 to 1825, The Statutes of the Realm was published, providing for the first time the authoritative collection of acts. In 1816, both Houses of Parliament, passed resolutions that an eminent lawyer with 20 clerks be commissioned to make a digest of the statutes, which was declared "very expedient to be done." However, this was never done.
In 1850, the Interpretation Act 1850 (13 & 14 Vict. c. 21) was passed, which consolidated previous acts of parliament relating to statutory construction and simplify the language used in acts of parliament.
At the start of the parliamentary session in 1853, Lord Cranworth announced his intention to the improvement of the statute law and in March 1853, appointed the Board for the Revision of the Statute Law to repeal expired statutes and continue consolidation, with a wider remit that included civil law. The Board issued three reports, recommending the creation of a permanent body for statute law reform.
In 1854, Lord Cranworth appointed the Royal Commission for Consolidating the Statute Law to consolidate existing statutes and enactments of English law. The Commission made four reports. Recommendations made by the Commission were implemented by the Repeal of Obsolete Statutes Act 1856 (19 & 20 Vict. c. 64).
On 17 February 1860, the Attorney General, Sir Richard Bethell told the House of Commons that he had engaged Sir Francis Reilly and A. J. Wood to expurgate the statute book of all acts which, though not expressly repealed, were not in force, working backwards from the present time. From 1860 to 1889, Statute Law Revision Acts were passed to repeal enactments which had ceased to be in force or had become necessary, substantially reducing the volume of the statute book.

## Passage

The bill had its first reading in the House of Lords on 27 May 1889, introduced by the Lord Chancellor, Hardinge Giffard, 1st Baron Halsbury. The bill had its second reading in the House of Lords on 24 June 1889 and was committed to the Standing Committee for Bills relating to Law, &c. which met and reported on 27 June 1889, with amendments. The amended bill was committed to a Committee of the Whole House, which met and reported on 23 July 1889, without amendments. The amended bill had its third reading in the House of Lords on 26 July 1889 and passed, without amendments.
The bill in the House of Commons on 3 August 1889. The bill had its first reading in the House of Commons on 1 May 1889, presented by George Howell MP. The bill had its second reading in the House of Commons on 14 August 1889, and was unopposed by the government. The bill was committed to a Committee of the Whole House, which met on 24 August 1889 and reported on 26 August 1889, with amendments. The amended bill had its third reading in the House of Commons on 26 August 1889 and passed, with amendments.
The amended bill was considered and agreed to by the House of Lords on 27 August 1889.
The bill was granted royal assent on 30 August 1889.

## Legacy

Section 41 and the schedule were repealed by section 1 of, and the schedule to, the Statute Law Revision Act 1908 (8 Edw. 7. c. 49).
Without prejudice to section 17(2)(a) of the Interpretation Act 1978, a reference to the Interpretation Act 1889 or to any provision of that act, whether occurring in another act, in subordinate legislation, in Northern Ireland legislation or in any deed or other instrument or document, must be construed as referring to the Interpretation Act 1978, or to the corresponding provision of the Interpretation Act 1978, as it applies to Acts passed at the time of the reference.
The Interpretation Act 1889, except section 5 thereof (which related to the meaning of "parish") applied to the Interpretation Measure 1925, and to all measures passed by the Church Assembly after that measure, in like manner as it applied to an act of Parliament, and as if that measure and those measures were acts of Parliament.
In 1978, the act was wholly repealed by the Interpretation Act 1978, which implemented recommendations by the Law Commission.

## Provisions
### Re-enactment of existing Rules
#### Section 1

Section 1 of the act provided that for all acts passed after 1850, unless the contrary intention appears:
* Words importing the masculine gender be deemed and taken to include females, unless expressly provided
* The singular be deemed to include the plural and the plural to include the singular, unless expressly provided.
* The same rules shall be observed in the construction of every enactment relating to an offence punishable on indictment or on summary conviction.
This reflected section 4 of Interpretation Act 1850 (13 & 14 Vict. c. 21).
Section 1(1) of the act was updated in the Interpretation Act 1978 to work operate both ways.

#### Section 2

Section 2(2) of the act provided that the word "person" should include body corporates unless the contrary intention appears and that penalties are also able to be paid to body corporates.

#### Section 3

Section 3 of the act provided definitions of words in all acts passed after 1850, unless the contrary intention appears:
| Expression | Provision |
| "month" | shall mean calendar month. |
| "land" | shall include messuages, tenements, and hereditaments, houses, and buildings of any tenure. |
| "oath" and "affidavit" | shall, in the case of persons for the time being allowed by law to affirm or declare instead of swearing, include affirmation and declaration, and the expression "swear" shall, in the like case, include affirm and declare. |
This section reflected section 4 of the Interpretation Act 1850 (13 & 14 Vict. c. 21).
Section 3 was updated in the Interpretation Act 1978 to be appropriate for Scotland and reflect modern definitions of land, including in the Town and Country Planning Act 1971, Town and Country Planning (Scotland) Act 1972 and the Community Land Act 1975, which covered buildings and structures, lakes, rivers and foreshore, particular estates or interests in land and easements (servitudes in Scotland) and other rights over and in land.

#### Section 4

Section 4 of the act provided that for all acts passed after 1850, the word "county" shall be construed as including a "county of a city and a county of a town", unless the contrary intention appears.

#### Section 5

Section 5 of the act provided that for all acts passed after 1850, the word "parish" as respects England and Wales shall mean a "place for which a poor rate is or can be made, or for which a separate overseer is or can be appointed", unless the contrary intention appears.
Section 5 of the act was repealed by section 69(1) of, and schedule 8 to, the Rating and Valuation Act 1925 (15 & 16 Geo. 5. c. 90), as to England and Wales, except as to the administrative county of London and Isles of Scilly (ss. 70(1) and (2)).
This section was repealed as to the Isles of Scilly by the Isles of Scilly Order 1927 (SR&O 1927/59), p. 1500.

#### Section 6

Section 6 of the act provided that for all acts or orders of council after 1850, the word "county court" as respects England and Wales shall mean a court under the County Courts Act 1888 (51 & 52 Vict. c. 43), unless the contrary intention appears.

#### Section 7

Section 7 of the act provided that for all acts relating to Scotland, unless the contrary intention appears:
| Expression | Provision |
| "sheriff clerk" | shall include steward clerk. |
| "shire," "sheriffdom," and "county" | shall include any stewartry in Scotland. |

#### Section 8

Section 8 of the act provided that every section of an act shall have effect as a substantive enactment without introductory words.
This reflected section 2 of Interpretation Act 1850 (13 & 14 Vict. c. 21). Previously, many acts of parliament, including this act, would prefix each section with a clause such as "And be it further enacted", "provided always" or "Provided always and it be enacted."

#### Section 9

Section 9 of the act provided that all acts passed after 1850 shall is a public act to be judicially noticed as such, unless the contrary intention appears.
This reflected section 7 of Interpretation Act 1850 (13 & 14 Vict. c. 21).

#### Section 10

Section 10 of the act provided that any act may be altered, amended or repealed in the same session of parliament.
This reflected section 2 of Interpretation Act 1850 (13 & 14 Vict. c. 21). Previously, most acts of parliament would included a clause providing that "This Act may be amended or repealed in the present session of Parliament". This was thought to be necessary because all acts of a session were passed simultaneously on the first day of that session until 1793, and the House of Commons had a rule by which decisions of the whole house could not be reversed in the same session.

#### Section 11

Section 11 of the act provided that where an act passed after 1850 repeals a repealing enactment, it shall not revive any enactments, unless words are added reviving that enactment. Section 11 of the act also provided that where an act passed after 1850 substitutes provisions for an enactment, the repealed enactment shall remain in force until the substituted provisions come into operation.
Section 11(1) reflected section 5 of Interpretation Act 1850 (13 & 14 Vict. c. 21). Under common law, once an act was repealed it was treated as if it had never been treated, with the exception of acts past and closed.
Section 11(2) reflected section 6 of Interpretation Act 1850 (13 & 14 Vict. c. 21). This was designed to save words in the commencement section, but has little relevance to modern legislation in which repeals are synchronised with replacements.

#### Section 18A

Section 18A of the act was inserted by the Government of India (Adaptation of Acts of Parliament) Order 1937 (SR&O 1937/230), p. 965.
So much of section 18A as provided that the expression "Governor-General", in relation to the period between the commencement of Part III of the Government of India Act 1935, and the establishment of the Federation of India, meant the governor-general in council, did not apply to section 6 of the Indian and Colonial Divorce Jurisdiction Act 1940.
In section 18A(2), the words "or the Government of Burma Act, 1935" were repealed by section 5(3) of, and part I of Schedule 2 to, the Burma Independence Act 1947.

#### Section 19

Section 19 of the act provided that for all past and future acts, the expression "person" shall include "any body of persons corporate or unincorporate", unless the contrary intention appears.

#### Section 20

Section 20 of the act provided that for all past and future acts, expressions referring to writing shall be construed as including references to "printing, lithography, photography, and other modes of representing or reproducing words in a visible form", unless the contrary intention appears.

#### Section 21

Section 21 of the act provided that for all past and future acts, the expression "statutory declaration" shall mean a declaration made by virtue of the Statutory Declarations Act 1835 (5 & 6 Will. 4 c. 62), unless the contrary intention appears.

#### Section 22

Section 22 of the act provided that for all past and future acts, the expression "financial year" shall mean as respects any matters related to the consolidated fund or money provided by Parliament or to the Exchequer, or to Imperial taxes or finance, the twelve months ending 31 March.
In the Republic of Ireland, this section was disapplied by section 2(3) of the Exchequer and Local Financial Years Act 1974.

#### Section 23

Section 24 of the act provided that for all past and future acts, the expression "Irish Valuation Acts" shall mean acts relating to the valuation of rateable property in Ireland.

#### Section 25

Section 25 of the act provided that for all past and future acts, the expression "ordnance map" shall mean a map made under the powers conferred by the Survey (Great Britain) Acts, 1841 to 1870 or the Survey (Ireland) Acts, 1825 to 1870, and acts amending the same, unless contrary intention appears.

#### Section 26

Section 26 of the act provided that for all past and future acts that authorise or require any document to be served by post, whether the expression "serve". "give", "send" or other is used, service shall be "deemed to be effected by properly addressing, prepaying, and posting a letter containing the document, and unless the contrary is proved to have been effected at the time at which the letter would be delivered in the ordinary course of post", unless contrary intention appears.
This brings in supporting provisions for acts which expressly authorise postal service. In common law, notices or documents given or served were required to be handed to the party concerned.

#### Section 27

Section 27 of the act provided that for all future acts, the expression "committed for trial" used in relation to any person shall, as respects England and Wales, mean "committed to prison with the view of being tried before a judge and jury, whether the person is committed in pursuance of section twenty-two or of section twenty-five of the Indicatable Offences Act, 1848 (11 & 12 Vict. c. 42), or is committed by a court, judge, coroner, or other authority having power to commit a person to any prison with a view to his trial, and shall include a person who is admitted to bail upon a recognizance to appear and take his trial before a judge and jury".
Section 27 was updated in the Interpretation Act 1978 to define "committed for trial" and to extend the definition to Northern Ireland.

Section 28 of the act provided definitions of the expressions "sheriff", "felony" and "misdemeanour" for all future acts, unless the contrary intention appears.
| Expression | Provision |
| "sheriff" | shall, as respects Scotland, include a sheriff substitute. |
| "felony" | shall, as respects Scotland, mean a high crime and offence. |
| "misdemeanour" | shall, as respects Scotland, mean an offence. |

#### Section 29

Section 29 of the act provided that for all future acts, the expression "county court" as respects Ireland shall mean a "civil bill court within the meaning of the County Officers and Courts Ireland Act, 1877 (40 & 41 Vict. c. 56)".

#### Section 30

Section 30 of the act provided that for all past and future acts, references to the sovereign reigning at the time of the passing of the act, or to "the Crown" shall be construed as references to the sovereign for the time being, binding on the crown, unless the contrary intention appears.

#### Section 31

Section 31 of the act provided that for all past and future acts, expressions used in orders in council, orders, warrants, schemes, letters patent, rules, regulations or byelaws made by an act shall have the same respective meanings as in the act conferring the power, unless the contrary intention appears.

#### Section 32

Section 32(1) of the act provided that where any future act confers a power or imposes a duty, that power may be exercised and the duty performed from time to time as occasion requires, unless the contrary intention appears.
This sub-section was originally enacted to counteract the risk of restrictive interpretation, but are not little more than statements of the obvious.
Section 32(2) of the act provided where any future act confers a power or imposes a duty on the holder of an office, that power may be exercised and the duty performed by the holder from time to time as occasion requires, unless the contrary intention appears.
Section 32(3) provided that where any future act confers a power to make any rules, regulations or byelaws, the power shall be construed as including a "power, exerciseable in the like manner and subject to the like consent and conditions, if any, to rescinding, revoke, amend or vary the rules, regulations or byelaws, unless the contrary intention appears."
Section 32 was updated in the Interpretation Act 1978 to extend the provisions to orders in council, orders and other types of subordinate legislation made by statutory instruments and to cover explicitly powers of amendment and revocation.

#### Section 33

Section 33 of the act provided that where an act or omission constitutes an offence under two or more laws, the offender shall be liable to be prosecuted under either or any of those laws but not twice for the same offence, unless the contrary intention appears.
This section eliminated the need for savings in acts that create new offences already occupied by other legislation or by the common law.

#### Section 34

Section 34 of the act provided that for all future acts the measurement of distance shall be measured in a straight line on a horizontal plane, unless the contrary intention appears.

#### Section 35

Section 35 of the act provided for the citation of acts.
Section 35(1) provided that acts may be cited by reference to the short title (with or without the reference), or by reference to the regnal year in which the act was passed, and where there are more statures or sessions than one in the same regnal year, by reference to the statute or the session, as the case may require, and where there are more chapters than one, by reference to the chapter. Section 35(1) also provided that any enactment may be cited by reference to the section or sub-section of the act in which the enactment is contained.
Section 35(2) of the act provided that where any future act contains such a reference, the reference shall be read as referring, in the case of statutes included in any revised edition of the statutes purporting to be printed by authority, to that edition, and in the case of statutes not so included, and passed before the reign of King George the First, to the edition prepared under the direction of the Record Commission, and in other cases to the copies of the statutes purporting to be printed by the Queen's Printer or under the superintendence of or authority of Her Majesty's Stationery Office.
Section 35(3) of the act provided that for all future acts, a description or citation of a portion of another act shall be construed as including the word, section, or other part mentioned or referred to as forming the beginning and as forming the end of the portion compromised in the description or citation.
Section 35(3) is the opposite to parliamentary proceedings where an amendment to leave out "from X to Y" leaves both X and Y standing in the text.
Section 35 was updated in the Interpretation Act 1978 to address modern practices of citing acts by calendar year and chapter number and to authorise citation of subordinate legislation, including by orders in council or by statutory instruments and to ensure references to enactments are as the act stands at the time of reference, not as originally passed.

#### Section 36

Section 36(1) of the act provided that for all past and future acts, the expression "commencement" shall mean the time at which the act comes into operation.
Section 36(2) of the act provided that where a future act, or any order in council, order, warrant, scheme, letters patent, rules, regulations or byelaws made, granted, or issued, under a power conferred by any such act, is expressed to come into operation on a particular day, the same shall be construed as coming into operation immediately on the expiration of the previous day.
Section 36(2) was updated in the Interpretation Act 1978 to reflect the modern practice of commencing different provisions of the same by order or statutory instrument.

#### Section 37

Section 37 of the act provided that where a future act does not commence immediately and confers powers to make any appointment, to make, grant or issue any instrument or to do any other things for the purposes of the act, that power may be exercised at any time after the passing of the act, so far as may be necessary or expedient for the purpose of bringing the act into operation.
This section was enacted to make it unnecessary to fend off challenges to commencement clauses of individual acts.
Section 37 was amended in the Interpretation Act 1978 to reflect the modern practice of commencing different provisions of the same by order or statutory instrument.

#### Section 38

Section 38 of the act contained the Westbury Saving present in the Statute Law Revision Acts, explicitly preventing any repeal from affecting the interpretation of any statute still in force and retaining any right, benefit, claim, liability, principle of law and court jurisdiction that had previously arisen under a repealed act.
Section 38 of the act had the same effect in relation to any repeal by the Judicature (Northern Ireland) Act 1978 of a statutory provision other than an act of the Parliament of the United Kingdom as it had in relation to the repeal by the Judicature (Northern Ireland) Act 1978 of such an act.
Section 38 was updated in the Interpretation Act 1978 to address ambiguity surrounding "and any other act", to cover references to enactments repealed and re-enacted, to reflect the occasional practice of temporary acts and cover savings in legislation such as the Prevention of Terrorism (Temporary Provisions) Act 1989 and to apply to acts of the Parliament of Northern Ireland.

### Supplemental
#### Section 39
