FACTBOX-Key past and future dates in the battle for ABN

(Reuters) - A Dutch court is due to decide on Thursday whether to uphold ABN AMRO's sale of U.S. unit LaSalle to Bank of America, potentially throwing into question ABN's $88 billion (44 billion pound) agreed takeover by Barclays.

A ruling against the U.S. deal could make it easier for a rival group of suitors led by Royal Bank of Scotland -- for whom LaSalle is a key asset -- to table a bid for the ABN group. But it could also trigger legal action from BoA, delaying any takeover outcome.

The following are key dates in the battle for ABN.

** UPCOMING DATES:

May 3 - The commercial court in Amsterdam is due to rule around 3 p.m. British Time on the sale of LaSalle Bank after shareholder group VEB said a sale without shareholder approval was unlawful and hindered a takeover by the RBS-led group.

May 4 - Seven days after notifying the ABN board the RBS consortium can make an unsolicited bid for ABN and publish its offer price.

May 6 - Under the terms of the LaSalle sale the deal closes at midnight, New York time, on May 6. Any suitors have until then to trump Bank of America's $21 billion (10.5 billion pound) offer. BoA then has another 5 working days to match any counterbid.
