New York, July 5 : By invoking the Supreme Court ruling on presidential immunity, former US President Donald Trump has won a timely reprieve by getting the court to agree to delay his sentencing till after the Republican Party Convention where he is set to be crowned the party's presidential candidate.

Without an objection from the prosecutors, Judge Juan Merchan agreed on Tuesday to postpone the sentencing to consider claims by Trump's lawyers that the top judiciary's ruling applied his conviction last month on 34 charges of falsifying his business records to cover up payments to a porn star.

The sentencing now postponed to September 18 was set for July 11 -- four days before the Republican Party Convention scheduled to be held from July 15 to 18.

Trump faced a maximum sentence of four years for each offence and if he were sentenced as scheduled on July 11, he would have faced in the worst-case scenario the prospect of being in prison during the party convention in Milwaukee in Wisconsin state.

The date now set by the court would also be after the next presidential debate between Trump and President Joe Biden on September 10.
