‘‘This is the first time in the history of Egypt that judges are assigned to investigate vote violations,’’ a ministry spokesman said at a news conference.
Judge Mahmoud Abu Shousha, a member of the commission overseeing the referendum, rejected the charges of voting irregularities.
He said it was impossible to replace judges with court officials during the supervision, and that all stations stayed opened for four extra hours to accommodate the long lines, dismissing claims that some closed early. He said more staff will be recruited for the second round to speed up the process.
‘‘We don’t know what to do with those who spread these lies,’’ he said at a news conference.
Many top Brotherhood officials have consistently characterized their critics as holdovers from the era of deposed president Hosni Mubarak. Most top judges are Mubarak-era appointees. The National Salvation Front is largely made of the Mubarak-era opposition, and Morsi’s critics also include some Islamists.
On Monday, Egypt’s Supreme Constitutional Court — the country’s most prestigious tribunal that is at the center of the Brotherhood’s conflict with the judiciary — denounced a statement by a Morsi aide in which it discussed the court under a ‘‘campaign’’ by ‘‘anti-revolutionary forces’’ to ‘‘overturn the gains of the revolution’’ against Mubarak.
Court spokesman Maher Sami accused Essam el-Haddad of ‘‘tarnishing’’ the court’s image and criticized him for writing the memo in English.
‘‘The Supreme Constitutional Court is asking why the president’s aide chose to address the foreign media,’’ he said. He added el-Haddad aimed at ‘‘toppling the court’s reputation internationally’’ and that the ‘‘crime of spreading false and provocative news is punishable by law.’’
El-Haddad, Morsi’s aide, denied the court’s accusations and described them as ‘‘baseless.’’
