has special rules for ''amicus curiae'' briefs sought to be filed in cases pending before it. Supreme Court Rule 37 states, in part, such a brief should cover "relevant matter" not dealt with by the parties which "may be of considerable help". The cover of an ''amicus'' brief must identify which party the brief is supporting, or if the brief supports only affirmance or reversal. The Court also requires that all non-governmental amici identify those providing a monetary contribution to the preparation or submission of the brief. Briefs must be prepared in booklet format, and 40 copies must be served with the Court.
The Supreme Court has seen a steady increase of amicus in its proceedings. In 2019-2020 97% included these filings with the sharpest increase coming after 1966 and only a few interventions in the earlier decades.
In the United States Supreme Court, unless the ''amicus'' brief is being filed by the federal government (or one of its officers or agents) or a U.S. state, permission of the court (by means of
motion for leave) or mutual consent of the parties is generally required. Allowing an ''amicus curiae'' to present

is considered "extraordinary". The court can also appoint its own ''amicus curiae'' if neither party supports the decision of the lower court, which it has done at least 44 times.

, the judge may appoint a lawyer as ''amicus curiae''. The lawyer is not retained by and does not represent the unrepresented party as such, but has a responsibility to ensure that points of law of importance to the party's case are brought to the attention of the court. For example, in the case of a criminal trial, the ''amicus'' will have the responsibility to ensure that the accused's right to make full answer and defence is upheld. Examples of situations that could call for the appointment of ''amicus'' could include a highly complex or technical trial, an unsophisticated accused or one with cognitive or psychiatric challenges, or an unruly and disruptive accused. In some cases, when an accused has retained counsel for part of the trial but then fires that counsel, and if the judge finds that ''amicus'' is needed, the former counsel may be asked to remain as ''amicus'', given their familiarity with the case.
Canadian courts may also appoint ''amici'' in situations in which a party is represented by counsel, but issues emerge in a highly specialized or technical area of the law, on which the judge wants submissions from a lawyer with special expertise in that area. For example, in ''R. v. Warren,'' 2022 ONSC 542, the judge appointed ''amicus'' to provide detailed submissions on the intersection between constitutional rights and prison law, explaining why this was normally outside the ken even of experienced criminal defence counsel.
Another situation in which ''amicus'' may be appointed is when an accused is self-represented in a trial for offences such as sexual assault or assault in a domestic violence context. An unrepresented accused has the right to cross-examine Crown witnesses, but it may be undesirable to permit him or her to personally cross-examine, for example, the complainant. As a result, the ''

[Van den Bossche, 2013, p. 263] Thus the only way for them to contribute to a WTO decision is through ''amicus curiae'' briefs. To date there is a divergence in approaches in the WTO as to the admissibility of such briefs.
The first WTO case to comprehensively examine the admissibility of ''amicus curiae'' briefs was US – Shrimp. The case concerned a ban by the US on imports of all shrimp and shrimp products not caught with turtle excluder devices. The panel at first instance rejected the two ''amicus curiae'' briefs that were submitted by environmental groups, on the basis they were not expressly solicited by the panel under Article 13 of the
Dispute Settlement Understanding of the WTO. This was overturned by the
Appellate Body who held a panel had authority to accept, consider or reject briefs under Articles 12 and 13 of the Dispute Settlement Understanding regardless of whether they were expressly solicited.
The issue was re-examined in US – Lead and Bismuth II which concerned the imposition of duties by the US on certain imported hot rolled lead and bismuth carbon steel from the UK. The Panel at first instance affirmed the position in the US – Shrimp case and accepted two ''amicus curiae'' briefs that were submitted. On appeal, the Appellate Body relied on Article 17.9 of the Dispute Settlement Understanding and Rule 16(1) of the Working Procedures for Appellate Review to create rules to accept ''amicus curiae'' briefs.
[Appellate Body Report, United States – Imposition of Countervailing Duties on Certain Hot-rolled Lead and Bismuth Carbon Steel Products Originating in the United Kingdom, WTO Doc WT/DS138/AB/R, AB-2000-1 (10 May 2000), 9�� 2/ref> This was deemed as the source of legal authority to accept such briefs by an Appellate Body.]
The next significant case to deal with ''amicus curiae'' briefs was EC – Asbestos, where the French government banned domestically produced and imported asbestos

products. Of the five ''amicus curiae'' briefs received by the Panel, only two that were submitted by the European Community, were accepted.[Panel Report, European Community – Measures Affecting Asbestos and Products Containing Asbestos, WTO Doc WT/DS135/R (18 September 2000), .12] The panel did not provide any explanation as to why they were accepted or rejected. On appeal, the Appellate Body relied on Rule 16(1) of the ''Working Procedures for Appellate Review'' to create additional procedures to deal with the ''amicus curiae'' briefs.[Appellate Body Report, European Community – Measures Affecting Asbestos and Products Containing Asbestos, WTO Doc WT/DS135/AB/R, AB-2000-11 (12 March 2001), 0�� 1] Of the 11 briefs submitted, the Appellate Body accepted none on the basis they failed to comply with these additional procedures.
