BERN. The first of September is the quietest of Switzerland’s law change dates, smaller than January or May, but this year it carries a reform of the federal prosecutor’s office, a pay package for Basel’s civil servants and a tighter data protection regime in the country’s largest canton. Here is what changes, and for whom.

The most consequential change is in Bern’s law enforcement machinery. The Office of the Attorney General enters a new organisation and administration regulation on Tuesday, a restructuring meant to run proceedings faster and to specialise the office for the cases that now dominate its intake: cybercrime and crypto related offences. The reform realigns the organisation, its staffing rules and its procedural processes, and follows years of criticism that Switzerland’s federal prosecutor was built for a slower era of financial crime.

The focus on digital crime is deliberate. Federal prosecutors have carried a rising caseload of ransomware, investment fraud and crypto theft files, many of them with victims abroad and evidence on foreign servers. The new structure creates clearer specialisation within the office, and it arrives as parliament prepares to debate the resources to match it.

Most of what changes on 1 September was decided months ago. Today is simply the date on the calendar when it starts to apply.

In Basel-Stadt, the wage package for the cantonal administration takes effect in its main parts. Entry level salaries rise, the cantonal police receive pay measures of their own, and cash allowances increase. The package is worth 18 million francs a year plus a one-off 4.3 million, and its journey was not smooth: the Grand Council first approved a larger version in April, then had to repeat the vote in May after it emerged that one vote had not been counted. A cost of living adjustment for all pay grades follows on 1 January 2027.

In the canton of Bern, the revised data protection law enters into force during September, with immediate effect for the communes. More than a thousand Bernese communes and communal bodies now fall directly under the supervision of the cantonal data protection authority. The four largest, Bern, Biel, Köniz and Thun, keep their own data protection offices. For smaller communes, the change ends a grey zone in which local data handling was supervised, in practice, by almost no one.

One deadline this month matters beyond the borders. On 11 September, central obligations of the European Union’s Cyber Resilience Act begin to bite for manufacturers and retailers selling digital products into the EU single market, including Swiss exporters: mandatory vulnerability management and a 24 hour reporting duty for security incidents. Non-compliance risks heavy fines or exclusion from the EU market. The Federal Council has tasked the Federal Office for Cybersecurity with presenting a Swiss consultation draft by the autumn.

And one familiar name quietly leaves the market. The online travel agency Ebookers ends its Swiss service on 2 September. Existing bookings and upcoming trips are not affected, the company says, but the Swiss website and app will no longer sell new holidays from Wednesday.

Behind the list sits a busier autumn. Parliament returns on 14 September for a three week session dominated by health premiums and the European package, and on 27 September voters decide on the neutrality and food security initiatives, with postal ballots already in households. The changes taking effect today are small print by comparison, which is usually how the rules that govern daily life arrive.

The advice from the cantons is the annual one: check the date on any letter from an authority this month. A rule that did not exist on Monday may well exist on Tuesday, and in Switzerland the assumption is that you knew.
