British Lawyers instructed by the "Mountain of Light" group to return the stone, said they would base their case on the Holocaust (Return of Cultural Objects) Act, which gives national institutions in the UK the power to return stolen art.
"光之山"團體委托的英國律師表示,此次訴訟會以《大屠殺（文化物品歸還）法案》為根據.這項法案賦予英國國家機構歸還被竊藝術品的權利.
Satish Jakhu, of Birmingham-based law firm Rubric Lois King, said they would make their claim under the common law doctrine of "trespass to goods", arguing that the government had stolen the diamond. He added that they would be taking their case to the International Court of Justice.
伯明翰律所Rubric Lois King的律師薩蒂什•雅庫（Satish Jakhu）表示,他們將依據習慣法有關"非法侵占他人所有物"的規定提出訴訟,并證明這顆鉆石確實是英國政府偷取所得.他還表示他們將會上訴至聯合國國際法院（International Court of Justice）.
Historian Andrew Roberts told the Mail on Sunday: "Those involved in this ludicrous case should recognise that the British Crown Jewels is precisely the right place for the Koh-i-Noor diamond to reside, in grateful recognition for over three centuries of British involvement in India, which led to the modernisation, development, protection, agrarian advance, linguistic unification and ultimately the democratisation of the sub-continent."
歷史學家安德魯•羅伯茨（Andrew Roberts）對《星期日郵報》（Mail on Sunday）表示："參與這起荒唐訴訟案的原告應當承認,英國王室皇冠是光之山鉆石的最佳歸處,這是對英國對印度長達300多年的幫助的感念和認可.這些幫助促進了印度的現代化,幫助印度不斷發展,給予了印度適當保護,推動了農業進步,使其語言統一,最終引領這塊次大陸走上了民主的道路."
According to legend, the gem can only be worn by God or women, and whoever wears the jewel will become extremely powerful, but if a man wears it, he will meet an unfortunate end.
據傳說,光之山鉆石只可由上帝或女性佩戴,佩戴者將擁有極大的權勢.但如果佩戴者是男性,就會厄運上身.
The jewel was also in the crowns of Queen Alexandra and Queen Mary. It remains in the Queen Mother's crown, which sat atop her coffin at her funeral in 2002.
光之山鉆石也曾被鑲嵌在亞歷山德拉王后（Queen Alexandra）和瑪麗王后（Queen Mary）的冠冕上.現在這顆鉆石仍嵌在伊麗莎白王太后的王冠上,這頂王冠在2002年王太后的葬禮上被放置在她的棺木之上.
The UK Government has so far rejected the claims.
到目前為止,英國政府否認印方的說法.
