Turkey's government plans to pass constitutional amendments that have pitted it against the judiciary in a week to 10 days and hold a referendum soon after, Justice Minister Sadullah Ergin said yesterday.

Public approval of the EU-inspired changes, which would make it harder to ban political parties and reform the way judges and prosecutors are appointed, would make it less likely for the Constitutional Court to strike down the amendments, Ergin told reporters.

"We object to the current structure of the judiciary because it overextends its powers and creates laws by overstepping the authority of the parliament," he said.

Prime Minister Tayyip Erdogan's AK Party, which has roots in a banned Islamist movement, has clashed with the secularist judiciary over efforts to introduce more government oversight of the Supreme Board of Judges and Prosecutors (HSYK), which appoints court officers.

Tensions were exacerbated last month with the arrest of a prosecutor and dozens of military officers for allegedly plotting to overthrow the government, wobbling financial markets worried about political stability in the $650 billion economy.

Earlier this month, the head of the Constitutional Court urged Erdogan to seek consensus rather than force through reforms to ease the strains generated by the detentions in the so-called Ergenekon coup investigation. The proposed package consists of "urgent and limited" amendments of 10 to 15 articles, including rules to curb the role of the Constitutional Court, Ergin said.

He would not specify whether the new rules would help the ruling AK Party avert a new closure case.

There is speculation in the media and among some investors that prosecutors could open another case to outlaw the business-friendly, pro-EU AK party, which narrowly escaped a ban in 2008 on charges it undermined Turkey's secular constitution.
