M&A transactions typically are transformational corporate events. From comparatively small private company transactions involving tens of millions of US dollars, to the largest multinational public company deals worth more than US$100 billion, the purchase or sale of any company involves significant risks and many uncertainties. M&A transactions impact the participants – directors, officers, employees, stockholders, creditors and customers – at every level of the corporate enterprise. And even the most strategic and well-planned M&A transactions sometimes fail to deliver the economic benefits that the parties anticipated at signing. These factors individually and collectively make M&A transactions ripe for litigation.

M&A litigation also raises many important policy issues, ranging from the appropriate role of corporate directors and stockholders both in making business decisions and in pursuing internal corporate misconduct, to the enforceability of contract provisions allocating various risks in connection with private company deals. The individual chapters that follow this introduction summarise how key jurisdictions around the world address these policy issues, and the extent to which they permit, encourage or limit M&A litigation. A survey of these chapters reveals a number of significant similarities, but also a number of important differences.

Common themes in global M&A litigation

Across common law and code law countries, there are a number of striking similarities with respect to how different jurisdictions address M&A litigation issues. For example, nearly every country addressed in this book expressly or impliedly embraces some form of what in the US is called the ‘business judgement rule’. Whether characterised as a formal legal presumption or simply the inherent reluctance of judges to interfere with discretionary business decisions, jurisdictions around the world show a strong tendency to protect or defer to corporate decision-making in the M&A context where the board acts in good faith, on an informed basis and without conflicts of interest.

Similarly, nearly every jurisdiction requires that corporate actors in the M&A context comply with some variation of the duty of care and the duty of loyalty. To uphold a challenged M&A decision, courts broadly require that directors and management make decisions on a fully informed basis, acting with the care of a reasonably prudent person under the applicable facts and circumstances. Jurisdictions consistently require that corporate representatives disclose or avoid conflicts of interest, such that M&A decisions are made in good faith in the best interests of the corporate enterprise, and not in the personal interests of any individual director or officer.

Another commonality across jurisdictions concerns the impact of a stockholder vote. After a board has approved an M&A transaction, separate approval by the stockholders is often required before the transaction can close. In most jurisdictions, where the stockholder vote is made on a fully informed basis, subsequent claims challenging the deal or the directors’ conduct in connection with the deal typically will be barred. This may be under a theory that the stockholder vote ‘ratified’ the board’s decision, that the vote ‘cleansed’ the transaction of any fiduciary duty issues or that stockholders are ‘estopped’ from challenging a transaction approved by a majority of investors.

One final recurring theme is that nearly every jurisdiction applies additional scrutiny with respect to responsive or defensive measures taken by a board in response to unsolicited takeover proposals. Some jurisdictions impose heightened judicial scrutiny on such measures, while others require separate stockholder or regulatory approval. But in all cases, jurisdictions recognise the increased risks and potential conflicts when a board acts in response to an unsolicited offer.

Notable differences in M&A litigation across jurisdictions

There also are a number of stark differences in M&A litigation across jurisdictions. For example, outside of the United States, few jurisdictions allow individual stockholders to pursue broad class or collective actions on behalf of all similarly situated investors, and, in particular, few jurisdictions permit class actions that require investors to affirmatively ‘opt out’ to avoid being bound by a judgment. Note, however, that certain European jurisdictions, including the UK and the Netherlands, have seen the emergence of collective action rules and procedures that apply in certain types of cases and that have similar features to class actions. The ‘internationalisation’ of US-style class actions may continue in the coming years.

Jurisdictions also vary significantly on the extent to which they permit individual investors to pursue ‘derivative’ actions to recover damages incurred by the corporation (some allow broad derivative rights, some do not recognise the procedure at all, and still others provide for minimum ownership requirements or court approval before an investor will be permitted to proceed).

Similarly, few jurisdictions permit stockholders to take broad pretrial discovery in M&A litigation, although most recognise some form of a books-and-records inspection right. The majority of courts also limit the ability of corporate defendants to resolve M&A litigation through early dispositive motion practice.

Jurisdictions also follow significantly varying approaches with respect to whether a corporation may limit liability for directors involved in M&A transactions through exculpatory by-law or corporate charter provisions. Some jurisdictions broadly allow such provisions; others find them void as against public policy; and others permit them for certain types of claims (eg, claims sounding in ordinary negligence or claims by outside third parties).

One final notable difference is the extent to which jurisdictions permit corporations to require stockholders to bring M&A litigation in particular forums. Certain jurisdictions permit corporations to mandate that stockholders bring M&A litigation in particular courts or even in arbitration, while others apply their general jurisdiction and venue rules.


Public company M&A litigation is most common in the United States and certain other countries discussed in this book. This appears to be because of class action and discovery mechanisms that permit an individual investor to pursue claims on behalf of other similarly situated investors. It is important to note, however, that US public company M&A litigation is currently undergoing significant changes. Certain leading courts have changed the law to afford greater deference to arms-length transactions approved by a stockholder vote. These changes appear to have brought US law more in line with that of other jurisdictions permitting collective actions. Following these decisions, there has been a slight reduction in the overall number of suits filed, along with changes to the types of claims being asserted and the venues where cases are being filed. The ultimate impact of these recent changes remains to be seen, however, both within and outside the United States.
