Schmuddi's answers notes that the Lexbase database only contains 4961 persons with Ali as one of their names. But if we read the Samhällsnytt article, we find that the number 9742 comes from the Verifiera database.
The Verifiera database contains cases not only from criminal and civil courts, but also from a number of administrative courts and similar bodies. This includes cases regarding:
- Disputes between landlords and tenants
- Decisions by the Swedish Tax Agency
- Decisions by municipal social services
- Decisions by the Swedish Social Insurance Office
- Involuntary care for addiction, psychiatric illness and minors
- Decisions by municipalities and county councils
- Decisions by The Swedish Migration Agency
- Various other decisions by government bodies
I would assume that most of these cases were brought to the courts by a private person to challenge a previous decision made by a government body.
I think the Migration Court cases is particularly noteworthy in this context. Anyone whose application for asylum or residency was declined can appeal their case to a Migration Court. The Migration Courts saw a big surge in cases during and after the European migrant crisis. According to this article 39 929 cases were brought to the Migration Courts in 2016 alone. The largest group of refugees arriving during this period was Syrian and Ali is an extremely common name in Syria. Since people appealing an asylum decision have already been declined once, it's likely that many of the people that these cases concern are no longer living in Sweden and would not be included in the quoted name statistics.
