Corporate and M&A

Within: Corporate and M&A

M & M Bomchil garners rave reviews for its ‘strong business understanding’, ‘tremendous response times’ and ‘in-depth legal knowledge’. The practice, which is led jointly by Marcelo Bombau and Javier Petrantonio, handles the full spread of M&A and corporate matters, with strong showings, recently, in the TMT, food-and-beverage and energy-and-natural-resources sectors. Highlights included advising Mosaic on the local aspects of its multi-jurisdictional acquisition of Vale’s fertiliser business.

Dispute resolution

Within: Dispute resolution

M & M Bomchil has a prominent dispute resolution practice, which is highly sought after for its specialist expertise in economic regulation (particularly energy issues), administrative law and complex arbitration. Guido Tawil, who is widely regarded as a ‘powerhouse in contentious energy matters’, heads the arbitration department; he recently acted in conjunction with Francisco Gutiérrez, María Inés Corrá, counsel Rafael Mariano Manóvil and newly promoted partner Federico Campolieti to represent a major multinational company in arbitration proceedings (under ICC, UNCITRAL and domestic rules) brought by local subcontractors arising from a state contract terminated by the government. In another administrative law-related case, Tawil and Corrá are assisting several wheat mills with various claims against the government concerning the lack of compensation for commercialising flour in the domestic market at subsidised prices. Javier Petrantonio heads the litigation practice and spearheaded the team (which also comprised counsel Hugo Lafalce and senior associate Martín Torres Girotti) that represented Carrefour in four significant claims stemming from the acquisition of Argentine supermarket chains. The group has also recently undertaken work for Aeropuertos Argentina 2000, Peugeot Citroën and Siemens.

    The Cyprus Investment Programme has been redesigned by the Cyprus Government in order to continue to attract high net worth individuals to settle and do business in Cyprus. The Key Changes will be applicable from the 15 th of May 2019 and include the following:
  • CYPRUS: Introduction of the General Healthcare System (GHS)

    Cyprus has introduced the General Healthcare System (GHS) that will cover its entire population. The GHS is a modern, patient-centric healthcare system with the aim of delivering equal and quality healthcare services to beneficiaries.
  • GRP Rainer Rechtsanwälte – Experience dealing with claims relating to D&O insurance

    In recent times, public pressure has continued to mount on managers in cases involving claims arising from damage or loss. Governing bodies and executives can insure themselves against the risk of liability by taking out a D&O insurance policy.
  • Antitrust Law Aspects in Ukraine

    Ukraine, like other European countries, developing a market economy on their territory, has incorporated antitrust regulations and legal mechanisms in its legislation to regulate and support competition, as well as rules to ensure fair competition. An integral part of the competition control is the control exercised by the Antimonopoly Committee of Ukraine over M&A transactions both in Ukraine and abroad, which may also affect Ukrainian domestic markets.
  • The Predicted End of Fiat Currencies

    Billionaire and crypto investor Tim Draper envisages a radical overhaul in payment systems; predicting that cryptocurrencies will replace fiat currencies within the next five years.
  • Termination of Employment for Good and Sufficient Cause

    In the case of Joseph Saliba vs Imperial Hotel (Goldvest Company Limited), the facts of the case revolved around Mr Saliba who was employed in various positions within the Hotel Imperial in Sliema until such hotel was acquired by Goldvest Company.
  • Legal Consultants in Dubai: Discussing Legality of Verbal Contracts

    A verbal contract is valued as much as the paper it is written on. While discussing and preparing for an important case, I found myself thinking the legalities of verbal contracts and the misconception towards their unenforceability.
  • DUE DILIGENCE: Importance In Acquisition

    Mergers and Acquisitions (M&A) can be as critical as it seems exciting for any entity's growth and development. If successful, it can assist both the companies to gain a significant share in the market and earn profits. If not successful, it can lead to a different story altogether. 
  • The Way Forward: Gender Neutrality and Gender Inclusion

    The principle of equality between men and women is a fundamental value constantly on the European Union’s agenda.  Ample EU institutes, programmes, and legislation provide for gender equality, and case law of the Court of Justice of the European Union (‘CJEU’) reaffirms the progress made in this respect. On a member state level, the enactment of gender neutral laws (particularly in the fields of inheritance law, marriage law, and employment law), may be considered as having reached its culmination in a number of EU member states, in the legal recognition of non-binary people. In turn, the European Parliament is now actively seeking to bring language evolution at par with gender inclusive legislation.
  • Abetting in Crime: Criminal accountability for parties involved

    NOT JUST A CRIMINAL ACT WILL MAKE YOU A CRIMINAL So, the plan is that "A will enter the apartment wearing women's abaya with a key provided by C, B will wait outside in the car, and once we complete the act, we will keep the money at D's place." The plan is simple, and everyone is aware of their role in the act.
