The euro slipped against the dollar on Thursday after a Greek court ruled the country's pension reform demanded by foreign lenders may be unconstitutional, stoking worries about Athens' ability to implement austerity measures needed to secure aid.
The common currency had earlier climbed near $1.30 after encouraging US economic data, which came a day before the all-important US monthly payrolls report, boosted equity prices and risk appetite. The euro fell 0.2 percent to $1.2938, after having earlier risen to a session high of $1.2982 on Reuters data. It remained higher against the yen and was up 0.3 percent at 103.71 yen. The dollar rose 0.5 percent to 80.12 yen, having hit a session peak of 80.17 and inching toward the four-month high of 80.36 struck on Reuters data last Friday.
