The official languages of the court are French and English. The hearings are public. Every decision is by a majority of the judges present at the hearing. The judgments are required to state the reasons on which the decisions are based. They are delivered in open court, and are printed and published in a regular series of reports. They are final and without appeal, but a judgment is binding only between the parties and in the particular case. Dis senting judges are entitled to deliver separate opinions.
Special chambers of five judges each are appointed by the court for three years to hear and determine labour cases arising under Pt. XIII. of the Treaty of Versailles and cases relating to transit and communications under Pt. XII. of the Treaty of Ver sailles. In such cases the judges are assisted by technical assessors. With a view to the speedy dispatch of business, the court forms annually a chamber of three judges, who, at the request of the contesting parties, may hear and determine cases by summary procedure.
Special pains are taken in the statute to ensure that in each case there shall be in the court some judge familiar with the laws, cus toms and peculiarities of each country which is a party to the controversy, and if in any case there is no member of the court coming from the country which is a party litigant, that party may name an additional judge to sit in the court in that case. For
this purpose several parties in the same interest are reckoned as one party only.
