Czech citizenship: conditions for granting, refusal of the application and security grounds

There is no entitlement to citizenship. Even someone who meets all the conditions receives it by a decision of the Ministry, not automatically. That is the first sentence you will find in every refusal, and it is true. The second truth is that the Ministry must give reasons for its considerations and the courts review them, with a single exception discussed below.

Conditions

Permanent residence for 5 continuous years, for EU citizens 3 years, or 10 years of authorised residence in total. And actual presence for at least half of that time.
Good character: no conviction for an intentional crime and no unsuspended sentence for a negligent one, at home or in the country of origin.
Czech language and civics: an exam, with exceptions for children, people over 65 and graduates of Czech schools.
Three years without a serious breach of the rules on residence, insurance, taxes, maintenance obligations.
Income and its source, not being a burden on the social security system.
Integration, whether family, work or social. The Supreme Administrative Court set aside the refusal of a man whom the Ministry faulted for a lack of work integration, although he had rental income and unchallenged social ties: the forms of integration are assessed together, not so that one missing form sinks the rest.

Defence

Against a refusal there is a remonstrance (rozklad) to the Minister of the Interior within 15 days, then a court action within two months. The court examines whether the Ministry considered everything you submitted and whether it gave reasons for its conclusions.

The exception: state security

If the Ministry refuses the application on the basis of a classified opinion of the police or an intelligence service that the applicant poses a threat to state security, the decision contains no reasons and is excluded from judicial review. The Constitutional Court has upheld this rule twice, and the Supreme Administrative Court can do nothing but dismiss the action. It is the only place in the whole of administrative law where you do not find out why. The only defence is prevention: a clean residence history, no contacts that could be read the wrong way, and a well-prepared application so that the Ministry has no reason to ask further.
