Lebanese Prime Minister Hassan Diab is suing the American University of Beirut (AUB), where he worked for 35 years as an academic in a dispute over his exit package, his spokesman said.
Diab presented his-long planned resignation in January - the month he became prime minister.
"... He asked for an exit package in line with common practices and precedents at AUB. This request was denied ...," the spokesman said.
AUB, which has been hit hard by Lebanon's economic meltdown, declined to comment on the case, Reuters reported.
Diab had "never made any special request for any payments to be made either in foreign currency or into foreign bank accounts. All AUB professors have their pensions paid in US dollars, from a AUB foreign account", the spokesman noted.
"What the PM expressed was only what was already stated in the AUB retirement plan regulations and policies."
President of private AUB, which was founded in the 1860s, told Reuters in May that Lebanon's catastrophic collapse represented one of the biggest challenges in the history of a university which has weathered many crises, including Lebanon's 1975-1990 civil war.
Lebanon is grappling with a crisis caused by decades of state corruption and bad governance. A hard currency liquidity crunch has led to an 80% weakening of the local currency since October.
