Former International Court of Justice deputy chief CG Weeramantry on Saturday emphasised the need for evolving an international law to ensure world peace and unity.
He was delivering the keynote address on the inaugural day of the four-day 7th annual global conference of top judicial functionaries including chief justices of about 75 nations, hosted by the Lucknow-based chain of the City Montessori School (CMS) in Lucknow.
The meet opened with a prayer by the school students "for safeguarding the future of 2 billion children living across the globe".
"The 20th century was a lost opportunity, but the 21st century would be the last opportunity to achieve the ultimate objective of establishing complete peace and unity among all nations of the world," Weeramantry told the gathering.
Weeramantry, also a retired judge of Sri Lanka's apex court, urged participants to carry the message of this meet to their respective countries and impress upon their lawmakers to get peace education included in the curriculum of their respective schools.
"Please take it seriously and strive to achieve the ultimate goal of establishing world peace."
"And the day we achieve that, Lucknow would carry the distinction of playing an important role in shaping human history," he added.
Earlier, inaugurating the meet, Justice VN Khare, a former chief justice of India, said, "the appeal made by CMS students has a special significance as its draws the attention of the entire world towards the children's rights for ensuring their safe future."
Delivering the welcome address, Justice Saghir Ahmad, a former judge of India's Supreme Court, praised the school for "writing a new chapter in human civilisation by raising major issues through its children."
Justice Graciela Dixon, chief justice of the Panama Supreme Court, spoke on the duties of the judiciary with respect to ensuring protection of the world's children.
