CAIRO  - Egypt’s dissolved parliament convened on Tuesday in defiance of the powerful military and the judiciary, amid a legal crisis triggered by a presidential decree to reinstate the Islamist-led assembly.

“We are gathered today to review the court rulings, the ruling of the Supreme Constitutional Court,” which ordered the house invalid, speaker Saad al-Katatni said. “I want to stress, we are not contradicting the ruling, but looking at a mechanism for the implementation of the ruling of the respected court. There is no other agenda today,” he added.

Last month, the Supreme Constitutional Court said certain articles in the law governing the parliamentary elections were invalid, annulling the house. The military, which ruled Egypt after Hosni Mubarak was ousted in last year’s popular uprising, then dissolved the house and took legislative control using a document granting the Supreme Council of the Armed Forces (SCAF) sweeping powers.

But on Sunday, President Mohamed Mursi, a former member of the powerful Muslim Brotherhood, ordered the lower house to reconvene just a week after taking the oath as head of state.

His move highlighted the power struggle between the president and the SCAF, after the constitutional declaration issued by the military basically defanged the post of president.

Mursi’s decree was hailed by those who want to see the army return to barracks, but it was slammed by those who fear an Islamist monopolisation of power as a “constitutional coup.”

Katatni said that parliament had referred the case invalidating the house to the Court of Cassation while the Supreme Constitutional Court was looking into cases put forward to annul Mursi’s decree.

The tension prompted US Secretary of State Hillary Clinton to call for negotiations.

“We urge that there be intensive dialogue among all of the stakeholders in order to ensure that there is clear path for them to be following,” she said at a news conference in Vietnam. The Egyptian people should “get what they protested for and what they voted for, which is a fully elected government making the decisions for the country going forward,” she added.

Clinton is due in Egypt on July 14 to express American support for the process of democratic transition in the US ally. Islamist parties including the Brotherhood’s Freedom and Justice Party - which Mursi headed before becoming president - and Salafist parties attended Tuesday’s parliamentary session.

But several MPs from liberal and leftist parties boycotted the gathering. Katatni insisted during a brief opening statement aired live on television that the house “respects the law and judicial rulings.”

On Monday, the Supreme Constitutional Court rejected Mursi’s decree, saying that all of its rulings were binding.

“All the rulings and decisions of the Supreme Constitutional Court are final and not subject to appeal... and are binding for all state institutions,” it said. The court stressed that it was “not a part of any political conflict... but the limit of its sacred duty is the protection of the texts of the constitution.” Several groups and politicians had criticised the court’s June ruling as politically motivated.

The SCAF backed the court on Monday, saying the rule of law must be upheld.

It underlined the “importance of the constitution in light of the latest developments,” the official MENA news agency reported.

Islamists scored a crushing victory in three-stage parliamentary elections held from November last year, with the Muslim Brotherhood, Mursi’s former organisation, heading the lower house.

But the military dissolved parliament last month after the top court made its controversial ruling just a day before the second round of the presidential poll that saw Mursi become Egypt’s first democratically elected head of state.

Instead of being sworn in before parliament, the 60-year-old Mursi took the oath on June 30 before the constitutional court.

The Muslim Brotherhood announced “a million-man march in support of the president’s decision and reinstating parliament” on Tuesday.

The presidency insisted on Monday that Mursi’s decree “neither contradicts nor contravenes the ruling by the constitutional court.”

The ruling does not need to be implemented immediately, said presidential spokesman Yasser Ali, arguing that the decision “takes into account the higher interest of the state and the people.”

German Foreign Minister Guido Westerwelle on a visit to Cairo said that he was confident Egypt would resolve its mounting power struggle.

“I have the impression that a solution can be found,” Westerwelle told reporters.

“There is still no guarantee that the way towards democracy will be successful but we want to do what we can to ensure that it succeeds. “The newly elected, first democratic president assured me that he does not aim to question the decision of the constitutional court but that this is rather about how to organise the ruling’s implementation,” he added.
