The Claim
“Overruled the ACT government when they legalised same sex marriage.”
Original Sources Provided
✅ FACTUAL VERIFICATION
The claim is factually accurate. The Abbott Coalition government did challenge the ACT's same-sex marriage legislation in the High Court, and the High Court ruled in the Commonwealth's favor on December 12, 2013 [1][2].
The sequence of events was:
- On October 10, 2013, Federal Attorney-General George Brandis confirmed the Commonwealth would challenge the ACT's Marriage Equality Bill in the High Court once it became law [1].
- The ACT's Marriage Equality (Same Sex) Act 2013 passed and came into effect on December 7, 2013 [2].
- The High Court heard the case on December 3, 2013, and delivered its judgment on December 12, 2013 [2][3].
- The High Court unanimously ruled that the ACT Act was "inconsistent with the Marriage Act 1961 (Cth) and was therefore of no effect" [3][4].
The constitutional basis for the decision was:
- Section 51(xxi) of the Constitution gives the Federal Parliament power to make laws with respect to "marriage" [3][4].
- The Marriage Act 1961 (as amended in 2004) defined marriage as "the union of a man and a woman to the exclusion of all others, voluntarily entered into for life" [4][5].
- The High Court held that the federal Marriage Act was intended to be a "comprehensive and exhaustive statement of the law of marriage" in Australia, leaving no room for concurrent territory legislation [3][4].
- As a result, 31 same-sex couples who had married in the ACT during the brief window (December 7-12, 2013) had their marriages annulled [2].
Missing Context
The claim omits several critical pieces of context:
1. The Marriage Act definition was passed with bipartisan support in 2004:
The Howard government introduced the Marriage Amendment Act 2004, which inserted the "man and woman" definition into the Marriage Act. This amendment passed with Labor's support—Labor did not oppose it [5][6]. The definition that the High Court relied upon to invalidate the ACT law was therefore not uniquely a Coalition creation, but a bipartisan position.
2. Labor governments had previously overruled ACT civil unions legislation twice:
The Howard government (Coalition) overturned ACT civil union legislation in June 2006 before it could take effect. When the ACT tried again in February 2007 with modified "civil partnership" legislation (removing all marriage references), the Howard government again threatened to disallow it [7]. The Rudd Labor government, elected in November 2007, took a different approach—allowing the ACT's civil unions to proceed—but maintained the same position on marriage itself [7].
3. The constitutional framework:
The claim frames the action as political interference, but the legal reality is more nuanced. Under Section 122 of the Constitution, the Commonwealth has plenary power to make laws for the government of any territory [8]. More importantly, under Section 109, when a federal law is inconsistent with a territory law, the federal law prevails [4]. The High Court found that the ACT Act was inconsistent with the federal Marriage Act and therefore invalid.
4. The High Court also confirmed federal power to legalize same-sex marriage:
Importantly, the High Court held that the Federal Parliament has constitutional power to legislate for same-sex marriage under Section 51(xxi), and that "under the Constitution and federal law as it now stands, whether same-sex marriage should be provided for by law is a matter for the Federal Parliament" [2][4]. This meant the Coalition was not preventing same-sex marriage indefinitely—it was asserting that only the federal parliament could make that change.
5. Attorney-General Brandis's stated rationale:
Senator Brandis stated: "Irrespective of anyone's views on the desirability or otherwise of same-sex marriage, it is clearly in Australia's interests that there be nationally consistent marriage laws" and "At the moment, the Commonwealth Marriage Act provides that consistency. The ACT's proposed law is a threat to that well-established position" [1].
Source Credibility Assessment
Original Source 1: ABC News article
ABC News is Australia's public broadcaster and is generally considered a reputable, mainstream news source. It has a statutory obligation to accuracy and impartiality under the ABC Act. The specific article cited is a factual report on the High Court decision [2]. This is a credible source.
Original Source 2: Australian Marriage Equality poll factsheet
Australian Marriage Equality (AME) was an advocacy organization campaigning for same-sex marriage legalization [9]. As an advocacy group with a clear position on the issue, their materials should be understood as representing a particular viewpoint rather than neutral reporting. This does not mean their information is inaccurate, but readers should be aware of their advocacy purpose when assessing framing and emphasis [9].
Labor Comparison
Did Labor do something similar?
Yes, Labor governments have taken similar positions on the constitutional relationship between federal and territory/state marriage laws:
1. The 2004 Marriage Amendment (bipartisan):
The Howard government's 2004 amendment to the Marriage Act, which defined marriage as between "a man and a woman," passed with Labor's support. Labor did not oppose this amendment [5][6]. This established the legal framework that was later used to challenge the ACT law.
2. The Rudd/Gillard Labor government position (2007-2013):
The Rudd Labor government (2007-2010) and Gillard Labor government (2010-2013) both maintained that marriage should be between a man and a woman. Both Prime Ministers Rudd and Gillard publicly opposed same-sex marriage during their terms [7]. The Gillard government did not move to legalize same-sex marriage, despite having the parliamentary numbers to potentially do so.
3. Howard government overruled ACT civil unions (2006):
The Coalition government under Howard used similar powers to overrule ACT civil union legislation in 2006, and threatened to do so again in 2007 [7].
4. Constitutional consistency across governments:
Both major parties have historically used the constitutional supremacy of federal marriage law to maintain a consistent national position. The Abbott government's action in 2013 was consistent with this established pattern—not a unique Coalition overreach.
Key difference: The Abbott government challenged the ACT law through the High Court, obtaining a judicial determination, whereas the Howard government had used the disallowance power under the Australian Capital Territory (Self-Government) Act 1988. However, both approaches served the same constitutional end of asserting federal supremacy over marriage law.
Balanced Perspective
While the claim is factually true that the Coalition "overruled" the ACT, this framing presents only one side of a complex constitutional and political issue.
The Coalition position:
- The Commonwealth Attorney-General argued that national consistency in marriage laws was in Australia's interests [1].
- The Coalition maintained that the federal Marriage Act provided such consistency and that the ACT law threatened it.
- The government sought a definitive High Court ruling rather than allowing legal uncertainty to persist.
The constitutional reality:
The High Court's decision was based on established constitutional principles. The Court found the ACT Act inconsistent with federal law, not merely because the Coalition wanted it so, but because of the constitutional framework that gives the federal parliament exclusive power over marriage [3][4].
The Labor context:
The Howard-era definition of marriage that underpinned the High Court decision was passed with Labor support. The Rudd and Gillard Labor governments (2007-2013) also opposed same-sex marriage. If the timeline had been different—if the ACT had passed this law in 2010-2013—the Gillard Labor government would likely have faced the same constitutional question and may well have reached the same conclusion.
The broader context:
Australia achieved same-sex marriage legalization in 2017 through a federal parliamentary vote following a national postal survey—not through state or territory legislation. The Coalition eventually allowed a conscience vote on the issue, leading to passage of the Marriage Amendment (Definition and Religious Freedoms) Act 2017. This suggests that the 2013 High Court decision was a temporary legal impediment, not an absolute political barrier.
Key context: This action by the Coalition was not unique to the Coalition—Labor had supported the same legal framework and held similar positions on marriage during their 2007-2013 government.

out of 10
The claim is factually accurate: the Abbott Coalition government did successfully challenge the ACT's same-sex marriage law in the High Court, leading to the law being struck down. However, the claim presents this as a partisan action without acknowledging:
- The legal framework used (the 2004 Marriage Act definition) was passed with bipartisan Labor support;
- Labor governments had previously taken similar positions on ACT relationship recognition legislation;
- The Rudd and Gillard Labor governments (2007-2013) also opposed same-sex marriage;
- The High Court decision was based on constitutional principles of federal supremacy, not merely political preference;
- The decision actually confirmed that the federal parliament had the power to legalize same-sex marriage—meaning the barrier was the political will of whichever party was in power, not the Constitution itself.
The framing implies an anti-LGBTQI+ stance unique to the Coalition, when in reality both major parties held similar positions on this issue during this period, and the constitutional logic applied would have been the same regardless of which party was in government.

High Court throws out ACT's same-sex marriage laws
Same-sex couples who wed in the ACT will have their marriages annulled after the High Court ruled against the laws. Craig Berry and his partner Ulises Garcia were among 31 couples who tied the knot after the laws came into effect last weekend but after five days, their marriage is over thanks to today's court ruling. "We're sad, but as far as I'm concerned my love for Uli hasn't changed, we're still married as far as we're concerned," Mr Berry said. The High Court in Canberra ruled that the ACT's laws were inconsistent with the Federal Marriage Act and therefore unconstitutional. The ruling is a victory for the Commonwealth, which had launched the appeal against the laws.
