The Statute of the International Court of Justice (hereinafter ICJ Statute) provides
two different forms of intervention for a third State who is willing to protect its own
interest in a case already brought before the Court. If a third State considers that it
has a legal interest which may be affected by the decision of the Court in the case,
the State is allowed to submit a request to the Court for permission to intervene in
accordance with Article 62 of the ICJ Statute. If a multilateral treaty is in question
regarding its interpretation before the Court, Article 63 grants a third State who is a
party to the treaty the right to intervene in the proceedings.
In the Whaling in the Antarctic case, Japan has argued that New Zealand’s
declaration of intervention under Article 63 of the ICJ Statute can be interpreted as
a strategy to avoid the burden of proving an “interest of a legal nature which may
be affected by the decision in the case,” as required under Article 62.
the Philippines has invoked Article 62 instead of Article 63 to intervene in the
Sovereignty over Pulau Ligitan and Pulau Sipadan case. It considered having an interest
of a legal nature which might be affected by the Court’s interpretation of certain
treaties to which it is the successor-in-interest of one party.
In the S. S. Wimbledon case, Poland also filed an application for permission to
intervene into the interpretation of the Treaty of Peace of Versailles, to which Poland
was then also a party, under Article 62 of the Statute of the Permanent Court of
International Justice (hereinafter PCIJ Statute).
From a further communications
with PCIJ, it appears to the Court that: “The Polish Government, abandoning the
to avail itself of the right conferred upon it, as a party to the Treaty of Versailles, by
Article 63 of the Statute.”
Poland did not insist that the grounds for justifying the
intervention under Article 62 should be taken into consideration.
