While Governor of the Netherlands Antilles, Struycken came into conflict with the Council of Ministers of the Netherlands Antilles, who wanted to install S.W. van der Meer as Minister of Justice. Van der Meer, who had his own law practice in Curaçao, did not agree to give up his practice as a lawyer completely, prompting Struycken to refuse to install Van der Meer. The Dutch Antillean government complained to the government of the Kingdom of the Netherlands about the governor's inappropriate involvement in government matters. The Netherlands government eventually agreed with the Antillean government. This affair resulted in a reorientation of the office of Governor of the Netherlands Antilles, which increasingly began to resemble the role of the constitutional monarch in the Netherlands.
