The law in Ireland regarding causes of action involving the internet is a rapidly growing area of law and litigation. This book examines issues such as defamation, data protection, e-commerce and intellectual property. This book examines key pieces of legislation such as the EU General Data Protection Regulation and Defamation Act 2009; forthcoming legislation such as the Harmful Digital Communications Act; and the EU ePrivacy Regulation, which aims to ensure stronger privacy rules for all electronic communications. Ireland has the European headquarters of many international IT and tech firms such as Google, Facebook, LinkedIn, Amazon, and Twitter. As such, many of the key cases involving such firms are being played out in Irish courts.
