Seven justices will hear the appeal. Judgment is expected to be reserved.

Britain's highest court is to debate whether soldiers in battle have the right to life, it was reported tonight.
The Supreme Court will investigate circumstances surrounding the death of Private Phillip Hewett in Iraq in July 2005 and examine whether troops in war zones are covered by Article 2 of the European Convention on Human Rights, which protects the right to life, The Independent said.
