Some of the existing browsers do not support the Java virtual machine, so when interested parties carry out electronic procedures with the Public Administrations (AAPP) they may encounter the disadvantage of not being able to sign with a digital certificate.
Law 11/2007, of 22 June, on electronic access of citizens to public services (already repealed), expressly included several principles, such as technology neutrality (article 4.i)), which have not been transferred in all of them in Law 39/2015, of 1 October, on common administrative procedure for public administrations, nor in Law 40/2015, of 1 October, on the legal regime of the public sector.
However, the dominant doctrine has repeatedly stated that in no case could the new regulations be considered to be a setback in both the recognition of principles and rights of citizenship. That is why, although not included in the new legislation, it is considered that the principle of technological neutrality (and others) is also part of the regulations on e-government.
For this reason, in order to guarantee the principle of technological neutrality, it would be advisable for the AAPPs to implement (or provide) a solution that allows citizens to carry out these electronic procedures regardless of the browser they use.
