Austria: Post M&A Disputes – Rescission of Acquisition Agreements

→ Michael Walbert
In recent times of crisis, M&A transactions have given rise more frequently to legal disputes between the parties to the acquisition agreement. And parties to M&A transactions are seeking more often rescission of the agreement instead of mere compensation against the counterparty.
Legal basis for rescission of acquisition agreements
Potential legal bases for contract rescission include mistake, laesio enormis (ie, shortfall of value by more than half), invalidity (eg, due to corruption or other criminal offences, collusion or abuse of the right of representation) and fraudulent misrepresentation. While rescission claims might also be based on breach of representation and warranties and tort law, claims for rescission on that basis are rarely seen in practice as they are usually excluded in the acquisition agreement.
Exclusion of rescission claims in the acquisition agreement
From a seller’s perspective, it is generally advisable to seek the express exclusion of claims for rescission of the acquisition agreement to the extent permissible under laws applicable to acquisition agreements. Under Austrian law, claims for rescission of an acquisition agreement based on mistake, breach of representations and warranties, tort law and laesio enormis can generally be excluded between entrepreneurs to the extent permissible under public policy principles.
The exclusion of claims clause in the acquisition agreement should specifically refer to the legal provisions governing the rescission claims to be excluded. Particular care needs to be applied in connection with exclusion of rescission claims under acquisition agreements involving natural persons, in respect of which applicable law might limit the validity of exclusion of rescission claims based on consumer protection policy considerations.
However, rescission claims based on invalidity due to criminal offences or due to violation of other core provisions or principles of mandatory statutory law, and rescission claims based on fraudulent misrepresentation, cannot be excluded by agreement between the parties under Austrian law, and probably not under the laws of many other jurisdictions.
To disclose or not to disclose?
If the purchaser discovers defects of the acquired business or shares after the closing of the transaction, the question often arises of whether the seller has adequately disclosed relevant facts or circumstances giving rise to the defect and, if not, whether the seller was obliged to disclose such facts or circumstances. Most commonly, fraudulent misrepresentation is committed by way of intentional non-disclosure or omission of material information or documents rather than by misrepresentation of false information.
In a recent case1, the Austrian Supreme Court confirmed that fraudulent misrepresentation can also be committed by way of intentional omission of facts and circumstances, if under generally accepted views and standards disclosure of the relevant facts and circumstances is required.
Unanswered questions
In theory, successfully rescinded agreements are unwound by each party returning to the other party what it received in the transaction. That, however, is a major challenge in case of transfer of a business that has been operated by the buyer following closing and has changed over time. Rewinding of an M&A transaction can be even more complex and challenging if the acquired business or shares have been resold or merged into another company, in which case return of the acquired business or shares to the seller has become impossible. While it is generally accepted among legal scholars that in such cases the buyer must return the value of the acquired assets or shares, or other adequate compensation, to unwind the acquisition agreement, there is little common ground as to exact calculation of the compensation to be paid by the buyer to the seller.
Conclusion and outlook
The Austrian Supreme Court has so far only confirmed the rescission of a business acquisition agreement in single cases in which the ruling was driven by the particular facts of the case. These cases provide little guidance on disclosure obligations of the parties in M&A transactions.
As a rule, however, the seller of a business should not be under a proactive or specific disclosure obligation if the documents and information relevant to the target are made available to the purchaser for review in the course of a due diligence. The seller is obliged to specific disclosure only in rare cases; for example, where the purchaser is unable to draw adequate conclusions from the information and documents disclosed in the course of the due diligence.
