Rough summary of the August 11 decision (found a crippled version in a pastebin but better than nothing - PDF still appreciated):
MACARAJA SAS (MSAS) operates the bank account for MtGox. Bank Credit Industriel et Commercial (CIC) intended to close MSAS' account and finally did so on July 15. MSAS was unable to find any new bank account with another bank after that.
MSAS asked Bank of France for another bank to go to and they referred them back to CIC.
CIC refused, stating that the account was closed because of doubts about a misuse of the account for operations that it believes are regulated. MSAS states it is regular trade business.
Court says CIC has to open an account for MSAS. Legality of MSAS doings should/could be investigated at a later point in time.
The August 26 decision as found in the pastebin is very hard to read due to low OCR quality. I'd summarize it as follows:
The bank wants to get rid of the account again. They roughly describe MSAS/MtGox business model and what Bitcoin is. They proceed with complaining that MSAS is acting like a payment service or a bank. (It seems that all that arguing was not fruitful and MSAS should be given back their bank account.)
The August 31 decision does not add anything to that:
CIC canceled MSAS account on Aug 23 and shut it down on Aug 27.
Court subsumes that the cancellation / shutting down of the account does not stem from any new reasons not already known and discussed.
Consequently, the court rules that the account is to reopen and has to be continued, albeit only for "basic services".
Bitcoin as is not touched as a subject.
EDIT: The "original" PDFs (see posting directly above), and especially that of the October 18 decision are still highly appreciated.
EDIT2: Added the August 31 decision.
