  • Sentencing guidelines for corporate manslaughter

    In February 2010 the Sentencing Guidelines Council (the SGC) issued definitive guidelines to courts on imposing appropriate sentences for corporate manslaughter and health and safety offences causing death. The SGC states that fines imposed on companies found guilty of corporate manslaughter should not fall below £500,000, while fines in respect of health and safety offences that are a significant cause of death should be at least £100,000. Crucially, the SGC declined to provide for a fixed link between the imposed fine and the turnover or profitability of the offending company.

    On 5th December 2018, the Austrian data protection authority ( Datenschutzbehörde , "DSB") issued a decision (DSB-D123.270/0009-DSB/2018) on data subject's right to data deletion according to Art 17 GDPR.

  • Consent or pay – a valid scheme under the GDPR?

    Media companies throughout Europe struggle with a difficult economic environment: Shrinking sales figures for print products, the digitalisation and consumer demand force publishers to offer their content also on the internet. However, generating money for online publications is not quite easy as – at least in Austria – online subscription against renumeration has not been well accepted by customers. This partially has its root in the lack of suitable micropayment means in the past and users thus getting acquainted to online information being offered for free. Thus, publishers have instead focused on financing their platforms by online marketing activities such as placement of banners. Nowadays such digital advertisement is usually targeted to the specific user. For this purpose, cookies are stored on the user's computer upon his first visit of the website, which then collect data about his location, technical equipment used and online behaviour. This finally allows to display specific, user targeted advertisements. However, such cookies may cause issues with applicable consent requirements under the telecommunication and data protection regulations:

  • Stop! Wait! Move! – No longer Stamp Duty for Residential Homes

    On 12 October 2017, right in a last minute attempt to win undecided voters for one of the political parties, the leaving members of parliament enacted a new tax law. While fundamental changes to the Austrian Tenancy Law had been vividly discussed between the socialist and the conservative parties in recent years, the new law on the abolition of stamp duty falls completely short of what could have been achieved.
