Signal fugitive convicts

Stichting Inlichtingenbureau

A resident who has been given a prison sentence and is trying to evade it is called a fugitive convict. These residents are not entitled to assistance. Municipalities must check this and, if necessary, stop the assistance benefit after investigation.

Responsible use

Goal and impact

Residents trying to escape their prison sentence or other custodial sentences are not entitled to benefits under the Participation Act and other laws. Based on information received from the IB, municipalities can stop welfare benefits or other benefits if they are unjustified.

Considerations

The 'Signal fugitive convicts' is part of the information service Concurrence signalling (see algorithm 'Concurrence signalling'). Only the specific points about 'Fugitive convict signal' are explained here.

Every month, the IB receives a report of fugitive convicts from the Central Judicial Collection Agency (CJIB). If this includes a Burgerservicenummer (BSN) of a social assistance beneficiary and there is an overlap between the period in which this person is registered as a fugitive and the benefit period, a signal is made available. So that the municipality can take the necessary action. An advantage of using this algorithm is that the municipality stops an assistance benefit if someone is not entitled to it. The algorithm ensures that a municipality only receives the data of their residents who receive welfare benefits and are fugitives.

This protects the privacy of citizens. An advantage of this algorithm is that it works much faster than when someone does it by hand. This saves a lot of time for municipal employees. Also, fewer mistakes are made this way.

Human intervention

For the IB itself, this algorithm does not involve human intervention. The algorithm executes rules devised by humans and is not 'self-learning'.

However, the IB does ensure that the processing process has been done properly.

The municipality decides whether and how to deal with a change.

Risk management

Citizen privacy is a major concern. That is why we periodically check whether there are risks and what can be done about them. This is called privacy impact assessment (PIA).

Legal basis

Article 13(1)(b) of the Participation Act which states that those who evade the enforcement of a custodial sentence or custodial order are not entitled to assistance.

Basis processing CJIB (as implementing agency under the Minister of J&V):

- Section 64(1)(k) and (12) and Section 68 of the Participation Act

- Section 45(1)(k) and (12) Income Support for Older and Partially Disabled Unemployed Workers Act (IOAW)

- Section 45(1)(k) and (12) of the Income Support for Older and Partly Disabled Former Self-Employed Persons Act (IOAZ).

Basis for processing IB:

- Sections 64(3) and 68 of the Participation Act

- Article 45(2) and (11) IOAW

- Article 45(2) and (11) IOAZ

- Section 63 of the Work and Income Implementation Organisation Act (SUWI), Section 5.24(1) and (3), SUWI Decree & Sections 6.2 and 6.6 of the SUWI Regulation

- IB-CJIB cooperation and exchange agreement

Basis for processing Municipalities:

- Section 13(1)(b) of the Participation Act.

- Chapter 5 'Implementation' and Chapter 6 'Powers and facilities of municipalities' Participation Act

Operations

Data

The municipality's benefit file (A):

- See Algorithm "Merge signalling" for this.

CJIB file delivery (B):

- BSN,

- Date passive approach,

- CJIB number.

Based on the BSN and date passive approach fields, the concurrence is determined and signals are created. Signal to municipality (D):

- Concurrence code (CJIB),

- Start date (the date passive approach),

- End date (the end date created by the system: the first day after BSN no longer appears in the CJIB list).

Technical design

Data processing streams:

A. A municipality delivers a file relating to the current social assistance population to the IB monthly via the secure client portal. A processing report is published after each delivery, listing any errors in the delivery;

B. The delivery of the CJIB file;

C. (Temporary) storage of the delivered BSN and corresponding signals in the social assistance population provision (client tracking provision);

D. In case of overlap of the source period with the benefit period, the IB makes a signal available to the municipality (and/or SVB). Depending on the reporting requirements set by municipality, a concurrence signal report is published on IB's secure customer portal.
