An accountability court on Tuesday summoned Pakistan Muslim League-Nawaz (PML-N) Vice-President Maryam Nawaz to appear in a case related to the fake trust deed in the Avenfield Apartments case.Judge Muhammad Bashir issued the notice to Maryam asking her to appear in court on July 19.According to the National Accountability Bureau (NAB), the trust deed Maryam presented in the Avenefield case was fake and have requested a trial against the PML-N leader for fraudulent documents.In 2017, a Pakistani team investigating former prime minister's Nawaz Sharif alleged illegal offshore properties – flagged in the Panama Papers – released its final report that mentioned ‘Calibri’.That report surmised that some of the documents it received from Maryam were forged , because they used Microsoft’s ‘Calibri’ font.In and of itself, that was not a problem. There was just the small matter of the documents being from 2006, when the font was not available for public use. Microsoft only released it for public use back in 2007.
