The first group of 11 people were charged under Section 186 of the Penal Code with obstruction of public servants in the discharge of public functions at Jalan Mengkuang between 12pm and 1.30pm on March 7.
The second group of two people were charged with committing the same offence during an earlier attempt to demolish the houses at an unspecified time on Feb 15.
The public servants in question are the police and officers from the Penang Islamic Religious Council (MAINPP).
The first group of 11 are Syazwan Sulaiman, 30; Mohd Fazli Rosli, 51; Mohd Ihsan Rifqie Mohd Zainudin, 25; Siti Dini Kamilia Haron, 19; Nurul Amani Muhamad Amin, 19; Siti Nurliana Haron, 30; Rozita M Medar, 47; Nuraila M Medar, 59; Roshidah M Medar, 43; Siti Musliha Haron, 25; and Ahmad Khan Hussain, 51.
They pleaded not guilty before magistrate Kalaiarasi Muniandy and were allowed bail of RM1,000 each with one surety.
The second group, consisting of Zikri Zulkifli, 30, and Mohd Ashraf Mustaqim Badul Munir, 33, also pleaded not guilty to the charge.
Their lawyer, Khaliq Mehtab Mohd Ishaq told the court that his clients had cooperated with the police, and asked for a reasonable bail amount.
Kalaiarasi allowed them bail of RM4,000 with one surety each.
Deputy public prosecutor Muhamad Syeqal Che Murat prosecuted the case against the 13.
The case involves the eviction of 46 families from Wakaf Abdul Cauder to make way for an apartment project.
MAINPP intends to build a 470-unit, 22-storey low-medium cost apartment on the 2.7-acre plot of land.
The evicted families will each be given a 1,000 sq ft home there while the rest will be rented out to low and medium-income earners.
The families have also been given close to RM4,000 in moving out allowance.
The settlers had been paying between RM2 and RM30 as rent to the council over the years.
