PENANGANAN TINDAK PIDANA KORPORASI TERKAIT PERTANGGUNGJAWABAN TINDAK PIDANA KORUPSI OLEH PT NINDYA KARYA (PERSERO) DITINJAU DARI PERMA NOMOR 13 TAHUN 2016
Authors: Rawiyakhirty Indira

Corporations as legal entities or subjects can give a major contribution in increasing economic growth and national development, but there are times when corporations commit various criminal acts (corporate crime) that have a detrimental impact on the state and society. In reality, corporations can be a place to hide assets resulting from criminal acts that are not touched by the legal process in criminal liability. The problem of corporate responsibility as a perpetrator of a crime is not a simple matter, considering that a corporation is a legal entity, not a person who can be subject to imprisonment. In addition, the problem also stems from the principle of no crime without error (geen straf zonder schold). Mistakes are known as mens rea or bad intentions that naturally only exist in natural people.

Mens rea is an element that is difficult to prove from a corporation that is considered to have committed a crime, considering that corporations can only take action through the organ of board of directors. Corporations can be considered to have committed a crime based on the actions of the person who supervises the management of the corporation. On December 21, 2016, the Supreme Court stipulates Supreme Court Regulation Number 13 of 2016 concerning Procedures for Handling Criminal Cases by Corporations (Perma No. 13 of 2016). The existence of Perma Number 13 of 2016 has become the basis for law enforcement to be more confident in taking action against corporations that commit criminal acts. This study aims to find out how criminal responsibility can be charged to PT Nindya Karya (Persero) as a perpetrator of corruption and how to apply Perma Number 13 of 2016 in handling corruption cases committed by PT Nindya Karya (Persero).

The method used is normative research. The criminal liability that can be imposed on PT Nindya Karya (Persero) is the principal crime in the form of a fine with a maximum provision plus 1/3 (one third). The determination of PT Nindya Karya (Persero) as a suspect in a criminal act of corruption is a concrete step in law enforcement in Indonesia in ensnaring corporations as perpetrators of criminal acts. This determination is a breakthrough in law enforcement, especially for the Corruption Eradication Commission (KPK) after the issuance of Perma No. 13/2016 which can be used as a guide in the implementation of handling corporate crimes.

Authors: Cavalcante Filho José Renan Miranda , Spir Patrícia Rodrigues Naufal , Cortez Gustavo Maldonado , Malveira Adib Saraty , Gaia Felipe Franco Pinheiro 
Published: March 2022

Background:
Histoplasmosis is a fungal disease endemic in some regions of the United States of America, Canada, and Latin America. The geographic characteristics, humidity, soil, and climate are responsible for such distribution. In Brazil, there are case reports of histoplasmosis throughout its territory, being considered an endemic region. It is considered an opportunistic disease, affecting mostly immunocompromised patients. To the present date, scientific publications dealing with pediatric cases of histoplasmosis are restricted to case series. Spinal cord injuries caused by histoplasmosis are rare, even in the adult population, being described in few studies.

Case Description:
The present report deals with a 4-year-old patient, from the southeast region of Brazil, who started a condition of fever, weight loss, cervicobrachialgia, and symmetrical tetraparesis, with evolution over 2 months. In the diagnostic investigation, she was found to have primary immunodeficiency and neuroimaging examinations showed a cervical spinal cord lesion at the level of C4-C6. The anatomopathological diagnosis of histoplasmosis was possible after surgery for decompression and biopsy of the lesion.

Conclusion:
According to our research, there are no reports in the literature that address the situation of spinal cord compression syndrome due to histoplasmosis in the pediatric population.
