FRANKFURT, March 3 (Reuters) - German engineering group Siemens has launched a fresh appeal against a Brazilian court ruling banning it from participating in government contracts for five years because of suspected bribery.
Siemens said the ban relates to tenders in 1999 and 2004 and internal administrative processes by the Brazilian Post and Telegraph Corporation (ECT).
Siemens started legal proceedings against the decision in 2010, but after several rounds of appeals a Brazilian court confirmed in late January Siemens' suspension from public tenders with immediate effect.
Siemens said the blacklisting affects a single-digit percentage of its business in Brazil. It has about 7,910 employees in Brazil and posts annual sales of close to 2 billion euros ($2.76 billion) there, according to its website.
