January 7 2022: On New Year’s Day, the Kerala High Court became the first  to go paperless.  The system has three elements: e-filing, paperless courts, and e-office
The filing of cases in the High Court will now be through the electric mode. However, a notice to this effect has also clarified that lawyers will still have to submit two sets of physical copies of the e-filed cases. In the case of vakalath, a scanned copy of the same should be uploaded.
An advocate dashboard shows the number of cases by the registered lawyer from the date commencement of his practice indicating their status along with orders or judgments issued if any. The dashboard also reveals the capacity in which the lawyer appeared in each case. The advocate calendar that shows the number of their cases listed on a particular day, which helps them plan a schedule.
After gathering inputs from lawyers regarding the difficulties in the e-filing system, a new feature has been added to the platform called the Quick e-filing procedure which includes only four steps to simplify the entire procedure.
One of the best features of the platform is that lawyers can view all the details and records presented to them or the opposite side in their cases and if required, take a printout of the same. Importantly, it also enables lawyers to clear defects online or to opt for video conferencing or hybrid mode for appearance in their cases.
The judges dashboard similarly indicates the total number of cases pending before the judge and a subject-wise list. It also shows the average disposal rate of each subject matter that helps the judge decide the time frame it would take to dispose of each matter.
In the High Court, the bench of the Chief Justice as well as six other courtrooms have been fully transformed into paperless smart digital courtrooms and in a few months, all the courts are expected to follow suit.
At district level, 2 magistrates  courts,  one at Thiruvananthapuram and the other at Kolancherry, have gone completely paperless (details  courtesy a LinkedIn Post by Legasis Services)
IndiaTechOnline sought feedback from  P.B. Sahasranamam, Sr Advocate, High Court of Kerala,  who embraced computer automation in his  chambers long before the courts  in Kerala did. He writes:
The e-filing system was introduced on 12th May 2021  as an option. Now from 1st January 2022, it was made compulsory. Whenever one enters a new technology there will be initial difficulties. But in a larger perspective, the implementation of e-courts is a beneficial system both for the judges and lawyers who are the main stakeholders. Judges will be able to flip pages quickly. This makes the system move fast. Of course, there will be difficulty in handling computer systems. But in a larger perspective, it has been found to be more useful to the court's system. Institutions like Green Tribunal are using the e-filing system for more than seven years. 
Initially, in order to find out a legal position, the lawyers have to browse the books of at last hundred years now with the help of computers one will be able to find out the precedents with the click of the mouse. The Video Conference systems has made by all the courts from 2019 in the pandemic situation. Now the Kerala High Court has even developed a special software V-CONSOL a special software that is exclusive for courts. It is different from the other usual conferencing softwares like Google Meet, Zoom, Webex, etc.
